Typical first pass tutorial process on Windows 10 where NONE of the extent how to articles actually tell you what you really need to do!
Typical first pass tutorial process on Windows 10
where NONE of the extent how to articles actually tell you what you actually really need to do! Here's what happened... 1. I read this post about an hour or so ago on the a.c.f newsgroup: o The nice thing about Audacity https://groups.google.com/forum/#!topic/alt.comp.freeware/S1IXPT3xk7g Which says this one line: "It can record the music from a youtube live stream." 2. Being infinitely curious about all tool functionality, I tried Audacity but failed even after reading a dozen web tutorials. 3. In the end, Audacity worked - but the point I'm making is that absolutely NONE of the tutorials explained the _necessary_ missing step (which is apparently required only on newer versions of Windows 10 as explained below). NOTE: If you're NOT on the later versions of Windows 10, most of the tutorials "should" work; but this is an example where they don't. === below is my ad hoc log just now attempting to do this === a. Googling for tutorials, here what I try (all failed), in sequence: https://www.computerhope.com/issues/ch001137.htm https://www.aimersoft.com/record-music/audacity-youtube.html https://www.labnol.org/software/record-streaming-audio/5000/ https://audacityguide.com/audacity-records-computer-audio https://audacity.wonderhowto.com/how-to/record-streaming-audio-from-internet-with-audacity-296750/ https://www.online-tech-tips.com/computer-tips/how-to-capture-save-record-or-download-streaming-audio-for-free/ https://www.widsmob.com/tips/capture-youtube-audio.html (worthless) https://www.easeus.com/screen-recording-tips/record-youtube-audio.html https://davescomputertips.com/how-to-record-internet-audio-with-audacity/ Note: Not only do they all omit important information, they conflict. This is the key reason why most tutorials suck. b. Find a short YouTube test video to record the audio stream of. o Bill Gates Remembers Richard Feynman - Bill Gates - 5/11/2018 https://youtu.be/HotLmqYFKKg Test that you "can" download just the M4A audio from that URL: youtube-dl.exe -f 140 https://youtu.be/HotLmqYFKKg [youtube] HotLmqYFKKg: Downloading webpage [youtube] HotLmqYFKKg: Downloading MPD manifest [dashsegments] Total fragments: 15 [download] Destination: Bill Gates Remembers Richard Feynman - Bill Gates - 5_11_2018-HotLmqYFKKg.m4a [download] 100% of 2.08MiB in 01:57 [ffmpeg] Correcting container in "Bill Gates Remembers Richard Feynman - Bill Gates - 5_11_2018-HotLmqYFKKg.m4a" move "Bill Gates Remembers Richard Feynman - Bill Gates - 5_11_2018-HotLmqYFKKg.m4a" gates_feynman.m4a Name: gates_feynman.m4a Size: 2174708 bytes (2123 KiB) SHA256: 748707B94311B10B19E45EAB99DEE3495E36BC91BDA062B3C5 02DDF1AD1B720B Doubleclick on the audio to ensure it plays (VLC, MPC-BE, WMP, whatever). c.

Do we still need to install LAME and/or FFMPEG separately? I don't know. This just loops back to the Audacity web site: https://sourceforge.net/projects/audacity/?s=install&i=lame-mp3 e. The "Stereo Mix" option "may" not be available if you do not have an external sound card (i.e., in an expansion slot) versus an integrated sound card (i.e., on the motherboard). I happen to have an expansion card mounted GeForce 210 graphics card & AMD integrated graphics GPU on the motherboard (i.e., I have both types). f. Start Audacity & check the version so we're on the same version: taskbar menu editor audio audacity Audacity:Help About Audacity == Audacity 2.4.2 g. Check that you "can" record as you'll need "Stereo Mix": Audacity:Edit Preferences Devices Recording Device: [?] Channels: [?] Mine said "No devices found" & nothing else was in the drop down entry. h. Set the computer so that you "can" record via "Stereo Mix": Win+R control View by: Category Hardware and sound Sound Playback Make sure that the Speakers are checked with a green checkmark. Hardware and sound Sound Recording Rightclick in a blank area & check "Show Disabled Devices" Mine said: Stereo Mix, Realtek High Definition Audio, Disabled When I rightclicked to set that to "Enabled" I got a notification: "Your privacy settings blocked access to the microphone" (It went away before I could click on the settings though.) Close & restart Audacity and "Stereo Mix (Realtek High Definiti)" shows up where it didn't show up before. You should now have: Audacity:Edit Preferences Devices Recording Device: [Stereo Mix (Realtek High Defini)] Channels: [2 (Stereo)] Press OK to close the preferences menu setup. i. In your favorite browser, start playing the YouTube video: https://youtu.be/HotLmqYFKKg j. In Audacity, attempt to record the video that is now playing: Audacity:Transport Recording Record I got: Error Error opening recording device. Error code: -9999 Unanticipated host error. k. So I switched off the VPN and tried again but got the same error. I should note I don't have a microphone, but the speaker plays youtube. l. Some tutorials say to set it to MME & others to WASAPI but both fail: Audacity:Edit Preferences Devices Host: (Mine was set to [MME]) Change that to: [Windows WASAPI] It still fails. m. Look up the colors of the 1/8th-inch stereo ports on my motherboard: Pink = Microphone in Blue Stereo in Green Speaker out n. One option I tried was to connect a 1/8th-inch stereo male-to-male loopback cable into the green (headphone out) & pink (mic in) ports. But it still failed. o. Giving up on the lousy tutorials, I resort to googling the error. (bearing in mind I do NOT have a microphone) https://github.com.cnpmjs.org/audacity/audacity/issues/663 https://appuals.com/audacity-error-code-9999-unanticipated-host-error/ https://www.windowsdispatch.com/fix-audacity-error-code-9999-unanticipated-host/ https://www.drivereasy.com/knowledge/fix-audacity-error-opening-sound-device-issue/ https://www.computerhope.com/issues/ch001194.htm https://www.techjunkie.com/audacity-error-opening-sound-device-how-to-fix/ https://sourceforge.net/p/audacity/mailman/message/36531828/ Possibilities (according to the above cites) a.

Ensure audio device settings in Audacity are configured correctly g. Turn off Software Playthrough in Audacity h. Update the audio driver i. Restart the Windows Audio Endpoint Builder service Win+R ms-settingsrivacy-microphone Turn everything on that you can. p. Now go back & play the video without VPN and press the Audacity "Record" Let it finish in 2:14 minutes & watch the pretty blue waveforms scroll. Then press the square Audacity "Stop" button. Note: I do NOT have a microphone, nor am I using the loopback cable; but I do have a 1/8th-inch jack tying the motherboard (green) output to a powered speaker on my desktop. q. Save it.

I have no microphone, was simply watching a youtube video and launched Audacity and hit the record button, then stopped recording and then saved as .mp3. On a Linum Mint desktop. Hi Nicodemus, I completely understand your experience, since it naturally "just works" for you by default (and I had "thought" it would just work for me too!). I too had figured it would only take a couple of minutes, instead of an hour (although documentation always takes a lot longer than just doing it). The problem is the "if then else" setup questions which need to be part of any decent tutorial, and which were not part of any tutorial that I found. What's not intuitive is that the latest versions of Windows 10, by default, disable the microphone, which, given neither of us _have_ a microphone, you'd "think" wouldn't matter. Even those these later versions of Windows 10 also disable any app to have access to that microphone - again, you'd "think" that wouldn't matter. And yet it does matter. o Win+R ms-settingsrivacy-microphone Worse, other gotchas "may" matter, such as: o Does the person have only an integrated sound card o Do they need a 1/8th-inch M:M greenink loopback mic-to-speaker jumper o Do we need to install LAME/FFMPEG anymore (the answer is no!) etc. Confusingly, some tutorials said to set the "Host" but they conflicted: Audacity:Edit Preferences Devices Host: o [MME]) o [Windows WASAPI] Where, I must confess, I don't even know what those letters mean! In summary, a good tutorial needs to add a few "tests" up front: a. Is the recording apparatus working (even sans microphone)? b. Does the integrated sound card or PCI extension card record audio? c. Is a male-to-male 1/8th-inch loopback jumper needed? What would be nice is if the team could supply those tests. o That way, the _next_ person has an easier time (which is always the goal) -- Part of the high cost of freeware is in figuring out how to use it. |

For me it says ALSA, on a Linux Mint system. It is a MBoard sound card. Maybe it has more to do windows10 by default making it difficult to use Audacity. I think I agree with you that two things made it harder for me 1. The later Windows 10 versions turn off the ADC audio access by default 2. Not a single tutorial mentioned that this was happening Luckily, the error message was seen by many others in the past o So googling for the error helped me solve the problem The good news is that by reporting that, I saved others the hassle. o The bad news is I'm not sure how useful this capability is. I mean, for YouTube, it's far easier to download the audio separately: o youtube-dl.exe -f 140 https://youtu.be/HotLmqYFKKg Where this capability of Audacity to convert streaming audio to an MP3 file may come in handy might be for _other_ streaming audio needs, outside of YouTube (since YouTube already has its very own well-honed downloader). What _other_ uses (than YouTube) do folks see for this Audacity capability? |

Thanks for clarifying that because the goal, always, is a tutorial that others can use so they would be up & running in minutes, not hours. I must admit that I don't even know what the "microphone" has to do with it, 'cuz I don't even _have_ a microphone on my desktop! Nonetheless, in my frustration, I turned on _everything_ I could: o Win+R ms-settingsrivacy-microphone Where it seems, from what you wrote, I only needed to turn on: o Allow desktop apps to access your microphone = on Ooops. I just tested that setting and you need _another_ setting: o Allow apps to access your microphone = On What's confusing is that my desktop doesn't even have a mic! Worse, the tutorials conflictingly said to set the "Host:" to: o Audacity:Edit Preferences Devices Host: [MME]) [Windows WASAPI] Where they don't even explain what the difference is. googling for what the terms mean: https://www.swee****er.com/sweetcare/articles/roland-difference-between-asio-wdm-mme-drivers/ o MME === Microsoft Multimedia Environment o WASAPI === Windows Audio Session API o WDM === Windows Driver Model o ASIO === Audio Streaming Input / Output o DirectSound === Direct Sound Looking it up, it apparently doesn't matter all that much, so the tutorials should just say that (instead of telling us to use one or the other). https://superuser.com/questions/895525/mme-windows-directsound-or-wasapi o MME: (multimedia events) The Audacity default and the most compatible with all audio devices. o Windows DirectSound: More recent than MME with potentially less latency. o Windows WASAPI: WASAPI is particularly useful for "loopback" devices for recording computer playback. 24-bit recording devices are supported. Playback is emulated using this host. It's not clear to me though _when_ you need "loopback recording": https://docs.microsoft.com/de-de/windows/win32/coreaudio/loopback-recording Audacity is a desktop app of the Win32 persuasion, rather than a Metro one. Ah. Thanks. I didn't know what a "desktop" app was, since, well, as you may know, I have zero "metro" apps (I don't even have a Microsoft Account), although I guess I have the "default" Microsoft apps which "may" be Metro. You also need that when doing things like WebRTC video conferences with a web browser, as that is a desktop application. I'm not sure what "WebRTC" is, but if you're doing a conference with a web browser, then you definitely _need_ an actual microphone, don't you? Looking up WebRTC: o https://bloggeek.me/what-is-webrtc/ "WebRTC enables voice communication to work inside HTML5 pages" OK. But you _still_ need a "real" microphone for that, right? What was unintuitive about "this" error was that you don't need a microphone for Audacity to record the audio. It's not intuitive you need the non-existent "microphone" to be enabled. https://www.techwalla.com/articles/m...r-wont-install Some pictures. https://i.postimg.cc/g0WdQhnf/audio-fix.gif Note that in that picture, _above_ of what you imaged is that there is yet _another_ microphone setting which _also_ must be turned on (I think). o https://i.postimg.cc/nhCyRNNW/audacity01.jpg So you need to turn on _two_ settings for Audacity to record streams o Win+R ms-settingsrivacy-microphone 1. Turn on "Allow apps to access your microphone" = On 2. Turn on "Allow desktop apps to access your microphone" = On Even if you don't have a microphone (which I don't have, for example).

That's interesting that you apparently had to update your sound card driver in order to get Audacity to record from streaming audio (if I understood you correctly). If so, this is interesting that you had to install a RealTek driver. o I didn't have to do that for Audacity to record streaming audio sans mic But... I've updated my drivers as described in gory detail in this thread o Tutorial: How to update a driver that Windows just doesn't want to update https://groups.google.com/forum/#!topic/alt.comp.microsoft.windows/a23fY9CM6rY Specifically, my RealTek driver is reported by Dumo freeware as: o Realtek High Definition Audio Realtek 6.0.8978.1, available 6.0.9018.1 o Realtek PCIe GbE Family Controller, Realtek 10.43.723.2020, available 10.45.928.2020 o Realtek USB 2.0 Card Reader, Realtek, 10.0.19041.31262, available 10.0.19041.31263 As shown in this Dumo freeware screenshot taken just now: o https://i.postimg.cc/Y00X4TFS/audacity02.jpg -- See also: o What's the one free Windows 10 driver update tool you prefer most & why? https://groups.google.com/forum/#!topic/alt.comp.microsoft.windows/-yDz26GC6zA o How do I know when the Windows driver verifier program is running? https://groups.google.com/forum/#!topic/alt.comp.microsoft.windows/NG4AzbPKsXs |

Microsoft uses terminology to suit the high-runner application. The permission is more likely to be "use the ADC on the HDAudio", meaning Mic_In, Line_In, Stereo_Mix. All of those are multiplexer inputs feeding a stereo ADC on the HDaudio chip. They could refine their permission to any degree they want, but there aren't any other choices than "Microphone", and the only way to make one control "fit" is if the control actually owns the ADC instead. If Microsoft said "permission to use the ADC", nobody is going to know what that is. Paul |

I googled what "high runner" meant, but found nothing; so I assume you mean "high end" applications, such as those which might require the sound card. The permission is more likely to be "use the ADC on the HDAudio", meaning Mic_In, Line_In, Stereo_Mix. All of those are multiplexer inputs feeding a stereo ADC on the HDaudio chip. That is a good explanation, which is that Microsoft uses the term "microphone" to mean the audio ADC input on the sound card. They could refine their permission to any degree they want, but there aren't any other choices than "Microphone", and the only way to make one control "fit" is if the control actually owns the ADC instead. If Microsoft said "permission to use the ADC", nobody is going to know what that is. I noticed that in some tutorials they mentioned that the "onboard" circuitry wouldn't allow Audacity to capture the streaming audio, while in others they didn't mention that complication. Since I have both onboard and the Nvidia GeForce graphics card, I wasn't sure which ADC is being used, where I 'think' I'm using the on-board ADC because the only sound jacks 1/8th-inch photo plugs are on the motherboard (the Nvidia GeForce 210 has digital output but no stereo jacks). In summary, I'm not sure how useful converting a YouTube audio to MP3 is (using Audacity) since it can be more easily downloaded as an M4A with youtubedl.exe; but there "might" be a use (somehow) of Audacity being able to save streaming audio from other applications (e.g., Zoom, WebRTC, whatever). -- It's nice to have Audacity in our arsenal but I'm not sure how useful it is to capture streaming audio since we likely could capture it anyway. |

You need to select Stereo Mix as your sound source. +-----+ Mic ------------| | | | A D LineIn ---------| Mux |---- ADC ----- to CPU | | Stereo_Mix +----| | | +-----+ | | From CPU -- DAC --+-- LineOut } | +-----------------------+ Stereo_Mix is a loopback signal. It takes a "copy" of what is coming from LineOut and routes it back to the input multiplexer. It's a feature in every HDAudio chip (like the motherboard 48 pin square chip in the corner). Thus, to record streaming audio, that audio going out the analog speaker connector, you need to select Stereo_Mix as seen in Audacity. Any mixer setting on Record block (Record in Windows icon in corner), the Stereo_Mix has to be turned up enough to hear it. Remember that picture I made yesterday ? It had a picture of Stereo_Mix in it for a reason. That wasn't a lark on my part. The Stereo_Mix is part of your request for recording audio from a Youtube session, without using youtube-dl and "cheating" to get it. We have to assume someday the RIAA will cut off as much recording capability as possible, and for a while at least, analog will work. I installed the RealTek driver over top of the Microsoft driver, in order to bring back the Stereo_Mix in my Win10 20H2 setup. ******* When we use that foot-long, 1/8" male to 1/8" male cable for recording, it looks like this. +-----+ Mic ------------| | | | A D LineIn +----| Mux |---- ADC ----- to CPU | | | | /-| | | +-----+ | | From CPU -- DAC --+-- LineOut } | +-----------------------+ 1/8" male to 1/8" male cable You can use a cable to take the place of Stereo_Mix, and then you'd select LineIn as your recording source in Audacity. This would be the case, if for example, Windows 10 buggered your Stereo_Mix capability with its clumsiness and stupidity. Not everyone has one of those cables. They might come with some TV tuner card perhaps. Paul |

Where LineOut & StereoMix are, somehow, intertwined Somehow, when I set Audacity to record from "Stereo Mix", (and if I'm playing a twitter streaming feed in my browser), but if I do NOT plug a "disconnected" cable into LineOut, then Audacity gets no signal to record. However, when I set Audacity to record from "Stereo Mix", (and if I'm playing a twitter streaming feed in my browser), and if I also plug a "disconnected" cable into LineOut, then Audacity DOES get a signal to record. I guess what your diagram is showing is that StereoMix is disconnected from LineOut unless a 1/8th-inch plug is used to "connect" them? Is that right? If so, then by putting the 1/8th-inch plug into the "LineOut" jack, that connects the twitter feed coming from the DAC to the "StereoMix" feed which then goes to the ADC to the CPU (???) and then from there, to Audacity as its digital input (???) Stereo_Mix is a loopback signal. It takes a "copy" of what is coming from LineOut and routes it back to the input multiplexer. It's a feature in every HDAudio chip (like the motherboard 48 pin square chip in the corner). I looked on my motherboard but don't see a 48-pin square chip in any of the corners, but I think I'm getting your point that the "StereoMix" is a loopback of LineOut to the ADC (and then to Audacity). Thus, to record streaming audio, that audio going out the analog speaker connector, you need to select Stereo_Mix as seen in Audacity. I did select "Stereo Mix" since all the tutorials suggested that o But I didn't know why The choices I have in Audacity a o For Host [MME] (Microsoft Multimedia Environment) Recording choices are [Stereo Mix] or [Microsoft Sound Mapper] o For Host [Windows DirectSound] Recording choices are [Stereo Mix] or [Primary Sound Capture Driver] o For Host [WASAPI] (Windows Audio Session API) Recording choices are [Stereo Mix] or [Digital Output loopback] or [Speakers] The good news is that they all have "Stereo Mix" as a choice. Any mixer setting on Record block (Record in Windows icon in corner), the Stereo_Mix has to be turned up enough to hear it. I don't understand that statement. Remember that picture I made yesterday ? It had a picture of Stereo_Mix in it for a reason. That wasn't a lark on my part. The Stereo_Mix is part of your request for recording audio from a Youtube session, without using youtube-dl and "cheating" to get it. We have to assume someday the RIAA will cut off as much recording capability as possible, and for a while at least, analog will work. I think I get it that "stereo mix" is a loopback of the analog signal _back_ into the ADC, is that what you're trying to teach me? With the 1/8th-inch plug in place, is this sequence correct yet? a. The digital stream comes in from the browser twitter feed b. That digital stream goes to the DAC preamp output c. That DAC preamp output goes to LineOut (to go to powered speakers) d. If (and only if) a 1/8th plug is plugged into LineOut e. Then that DAC preamp output also loops back to the ADC input f. Where the ADC converts the analog lineout to a digital stream g. Which is then fed to the "StereoMix" input of Audacity I installed the RealTek driver over top of the Microsoft driver, in order to bring back the Stereo_Mix in my Win10 20H2 setup. What does the "mix" mean in the term "Stereo Mix"? I get what "stereo" means (i.e., 2 audio channels) but what's the "mix"? a. Does the "mix" mean a mix of the two audio channels? b. Or does the "mix" mean a mix of line out and line back in via loopback? When we use that foot-long, 1/8" male to 1/8" male cable for recording, it looks like this. +-----+ Mic ------------| | | | A D LineIn +----| Mux |---- ADC ----- to CPU | | | | /-| | | +-----+ | | From CPU -- DAC --+-- LineOut } | +-----------------------+ 1/8" male to 1/8" male cable You can use a cable to take the place of Stereo_Mix, and then you'd select LineIn as your recording source in Audacity. This would be the case, if for example, Windows 10 buggered your Stereo_Mix capability with its clumsiness and stupidity. Is that why they suggested that physical male-to-male loopback cable here? https://davescomputertips.com/how-to-record-internet-audio-with-audacity/ Not everyone has one of those cables. They might come with some TV tuner card perhaps. I have an extensive cable box, like most people here. o It even has RS232 cables in it, and SCSI cables too.

What's needed to record the output, is a path to get back to the input side, and to the ADC. The Stereo_Mix method, uses a wire which is inside the HDAudio chip. Selecting that input, is a matter of configuring software the right way, so it will work. Every input has a level adjustment. You are adjusting the level to avoid overloading while recording. You adjust the gain, so the recording is loud enough. Take for example, you play a DVD and get a LineOut output that way. DVDs seem to be recorded really low, like -15dB or so. There seems to be no way to drive a lot of signal that way. When recording that DVD with Audacity, you need to adjust the level, for a pleasant recording. Audacity has a VU meter, so you can see the incoming voltage level. The VU Meter is there, so you can judge whether you've still got headroom, for a non-distorted recording. Inputs have mutes. Or, a level slider can be set at zero. The effect is zero volts on input and a very quiet recording, if either of those happen. ******* There is no particular reason for an interaction between LineOut/LineIn and Stereo_Mix. When you plug the 1/8" plug into a jack, the jack has a side contact. The side contact closure is detected on the HDAudio chip. It generates an event to the OS. The driver presents a prompt "Did you plug something into LineIn?" or similar. One of the side effects of plugging in LineIn, is it can be used to automatically switch the input mux in front of the ADC, so that LineIn is used. And whatever your previous choice was, is de-selected. The loopback path only exists for one chip choice at a time. To record through the RealTek Stereo_Mix, means the RealTek LineOut has to be used and playing the content on the analog computer speakers or similar. If the sound was going to your TV set over HDMI for example, maybe the NVidia video card HDAudio internal to the GPU is doing that. And there would be no "virtual wire" to get to the RealTek ADC/Mux. As a consequence, you have to think carefully about where that wire is. There is at least one "virtual cable" driver, which is a software technique for copying the Windows (output) mixer stream and making a "pin" of it. Then, in Audacity, the "pin" is offered as an "input choice". The virtual cable, in a sense, bypasses DACs and ADCs and "just gets the job done". This would be an alternative if someday soon, Microsoft finds a way of permanently removing the driver ability to get at the Stereo_Mix which is a hardware feature. From a DMCA perspective, Microsoft could also choice to block and prevent that "virtual cable" software from running. Summary: Plugging in 1/8" plugs to HDAudio jacks, has as a side effect, the "side contact" signals to the driver, that a change has occurred. And the driver can use this as an excuse to switch input or output settings, by signaling these facts to the OS handling things. Without software to receive "plug events", nothing would happen without software interference. The Stereo_Mix doesn't need that. It needs selecting Stereo_Mix in Audacity, to "wire up the input". But it also needs a signal going through the output side of that HDAudio chip, so that the signal can be copied. Stereo_Mix and the black wire, are two of the same. They're a path. The black wire also tickles the side contact on two jacks. The Stereo_Mix does not, so to get the Stereo_Mix to work requires two GUI actions at a minimum. Something to set up the input side. And some operation to get a signal onto the output, so you can copy it with a feature put there in the HDAudio chip for this. Paul |

All the while I thought the tutorials were missing only _one_ conditional "if then else" check, without knowing there are (at least) five of them! I've read your response four or five times, like a kindergarten kid watching a Disney movie, where each time I get a little bit more of what you're trying to inform me (as all this "Stereo Mix" stuff is new to me). This is perhaps the _simplest_ definition of "Stereo Mix" I've found: "Stereo Mix allows you to record exactly what was being output to your speakers, without going through any analog/digital conversion." https://mediarealm.com.au/articles/stereo-mix-setup-windows-10/ But Lord knows I've been scouring the Internet for better definitions: https://mediarealm.com.au/articles/stereo-mix-setup-windows-10/ https://winbuzzer.com/2020/04/25/how-to-record-windows-system-audio-with-stereo-mix-xcxwbt/ https://www.howtogeek.com/howto/39532/how-to-enable-stereo-mix-in-windows-7-to-record-audio/ *It seems 5 planets need to line up for a successful stereo mix recording.* (1) You need to turn on app & desktop app access to the "so-called" microphone: o Win+R ms-settingsrivacy-microphone == Microphone access = on (2) Your audio driver must be able to enable/disable the Stereo Mix selection: o Win+R devmgmt.msc Sound video & game controllers == Update driver https://www.realtek.com/en/component/zoo/category/pc-audio-codecs-high-definition-audio-codecs-software (3) You need to enable Stereo Mix (apparently, disabled by default in Win10): o Win+R mmsys.cpl Recording Stereo Mix == Enabled (4) You need your recording software to be able to use Stereo Mix o Audacity:Edit Preferences Devices Recording == Stereo Mix (5) And, you need to connect the "loopback" of LineOut to enable copying: o Plug in any 1/8-inch male plug into the lime green LineOut connector It's in understanding that final (fifth) planet lining up that I keep reading (and re-reading) your response, gleaning a bit more with each try. |
