Audio has issues with Windows Media Player but not in Virtualdub or SoundForge.
"muzician21" wrote in message
I'm including RAP since I imagine you've run into audio issues with Windows. I'm having an oddball problem I've never encountered before. Running XP Pro SP3, I find that when I play video with Windows Media Player there's static & popping in the audio. The same video plays fine in Virtualdub and with SoundForge. I tried uninstalling WMP and reinstalling, seemed to work at first but then developed the same issue. It used to work fine on this Windows install, the issue seems to have cropped up recently. What's the difference between how VirtualDub and SoundForge accesses/plays video audio and how WMP plays it? Of all the responses you've received so far, the one from Soundhaspriority is IMO right on. As he says in slightly different words: Part of the design of Windows includes the OS maintenance of a shared library of codecs (coder/decoders) for audio and video files. Thus, player software itself may be relieved of the chore of providing the dozens of codecs that can be required by the various media files that it processes. The player software itself can maintain a private inventory of codecs that it uses in preference to all or part of the shared system library of codecs. On many occasions there is an overlap between the shared system library of codecs and the various private libraries of codecs, whose resolution is up to the system and the player software. This is semi-organized chaos! It is quite possible that Virtualdub and Soundforge are decoding your video files using their own private codec libraries, while it is expected that Windows Media Player would use the main shared system codec libraries. The shared system codec libraries are unfortunately exposed to being updated from many sources, including the installation of an OS service pack. I would expect the OS Service pack to send things backwards, technologically. It is possible that one or more audio or video decoders that were beneficially installed by various player and/or editing software that you installed in the past, were overlaid by the latest OS Service Pack. Installing a video card also has the potential to update audio and video codecs. Some codecs have very similar overall functioning but may or may not exploit hardware performance features such as higher-level CPU instruction sets like MMX and SSE, or include codecs that exploit specialized hardware that is part of a video card. The whole business of decoding audio and video can be a bit of a nightmare because the problem has signficantly grown since the original codec infrastructure was designed. One approach would be to try reinstalling any other audio playing or editing software including Virtualdub and SoundForge. They were probably installed after the previous OS service pack was installed and may have beneficially overlaid some of the codecs that came with your PC. Re-installing your video card may or may not help. DVD playing software such as EasyDVD includes is own suite of codecs and reinstalling it may have a beneficial effect. A quick shotgun approach might be to install a large scale collection of encoders and decoders such as the "K-Lite Mega Codec Pack" which is a free download and IME remarkably effective as a codec problem solver despite the fact that it is more like using a shotgun to solve the problem, than to use a rifle which would be my preference. |

I'd try the XP Codec Pack first, as I've had some things go wonky in the past using K-Lite (or some elements therein). YMMV, of course, david |

VirtualDub does not instal any codecs (shared or otherwise), and has no private codec library. It uses the ACM (Audio Compression Manager) interface to decode audio. |

The thing is, I've never had this problem before - in 98, 98SE, XP Home, XP Media Center - which I understand is supposed to be plagued with issues. It wasn't an issue on previous installs of this same XP Pro disc that came with the machine. I've always found WMP to be dependable. I've now done a fresh install with the same XP Pro disc and it's doing it again. What I'm finding is if I bring up WMP first thing after a reboot, it appears to behave normally for a while. Plays .mp3, .wav, DV .avi, .mpg. However, at some point it starts doing it spontaneously. In fact I found it just did it playing through a playlist of 44.1 16 bit .wav files. Played through about the first 3 okay, after transitioning to the 4th track, the problem developed. I also find that if it's showing up in WMP it also shows up in Kmedia player and in Pinnacle Studio but *not* in Vegas Pro 8, Virtualdub or Soundforge. |

I'll try the same list of audio files in a fresh boot and using only Kmedia player and see if it crops up. |
