Has anyone here used the Cakewalk UA-1G USB audio adapter? While the Behringer
UCA-202 is good for the money, it does not provide audio level control for its
inputs. Usually that limitation is not a problem, but for the current project,
the level control will be helpful.

Also, I've used the Griffin iMic (Version 1) for a lot of ad hoc projects,
mostly involving playback. Over the weekend, I tried to use it on my HP
Elitebook 6930P, and the computer would not output audio through it even though
it provided input audio. The unit is quite dated, but so are most of my
computers. It acted like a driver was wonked, but I couldn't find any drivers
other than the default Windows drivers.

Why? The UCA-202 records all the significant bits it's capable of, and
overloads at a little less than 2V. IF you want to add a level control it
really needs to be an analog attenuator before the RCA inputs. You can
simply increase the digital file level after it's recorded, or some audio
programs will allow you to adjust the gain in real time if you're happy to
take the chance on clipping.

Either there is a problem with my unit, Windows installed the wrong driver, or
the input gain on the UCA202 is too low. For a totally unrelated reason, I
plugged the headphone jack of a portable FM radio into the UCA202. Even though
the volume on the radio was loud enough to finish destroying my hearing when
using headphones, the maximum level was -22db though the UCA202. If it had been
-12db, I wouldn't have complained. I expected it to be low, but not that low.

The UA-1G will be here tomorrow, so at least I'll have a point of reference.

OS is not specified, Windows 7 assumed. You need to specify for the
microphone that playback takes place via the usual soundcard. If you do not
do that windows assumes that the usb sound source also is capable of audio
playback.

Should be all you need. Look at second time at all the option pages for
sound.

Kind regards

It should give you DFS at approx 2V, IF you want digital FS at a lower
voltage you need a pre-amplifier, not a different driver.

Seems a bit low, but without knowing the FM radio output, it's hard to say.
Anything designed for high sensitivity earbuds for example will not get
anywhere near the 2V required by the UCA202 for DFS. Most ADC's without
pre-amps are even worse. (When the UCA202 is used in a professional set up
with the much higher levels, it requires an attenuator). An ADC with a mic
pre-amp front end is what you probably need, or simply use a cheap mixer as
a pre-amp if you have one instead. The UCA202 was mainly designed to be used
with a cheap Behrenger mixer, or the cheap Behrenger keyboards after all
