Does the labtec have a battery? It sounds like a power issue.

Depends on the soundcard, but the mic in input on some have the power on one of the stereo pins and the input on the other. If your mic is not wired up for that, it will have trouble. > > Looked around and found various asoundrc files with input configurations, > but nothing has worked so far.

If the labtec produces sounds into the mic in input, then it is not a soundcard/alsa issue, it would seem to me. > > Any ideas at all would be appreciated. > Thanks. > Tom > > -- William G.
