Mic in Skype works temporarily only

Hello guys,

I tried searching for the solution, did not find any so decided to post it here. I have quite a strange problem with Skype and Opensuse. First problem was that when I used microphone on Audigy 4 (from some reason recognised as Audigy 2) the sound which people received from me was very chirpy. This problem was solved easily, I just turned my on-board sound system on and started using micorphone from integrated card. And here comes my weird problem. Microphone works all right, but only for short period. After some time after I start talking to someone on Skype the microphone turns itself off, but I can still hear my interlocutors. The only solution is to go to Yast and restart sound system or to restart whole computer, both of which are not real solutions, but well, they sort of work. I’m using Opensuse 11.2 x64 and would be really glad if someone had a solution or clue as to what might be the reason of such a bizzarre behaviour.

I don’t use Skype nor use my mic for extended periods. Still, if that happened to me, I would look for two possible causes:
a. another application was launched suddenly seized the sound card and the mic, or
b. mixer level for capture changed unexpectedly.

I thought about that too, checked for these things anyway, unfortunately it seems the reason for my mic behavior lies somewhere else.

Does the mic work ok with arecord? Reference: Microphone - openSUSE
try see how long it lasts with: arecord -vv -fdat foo.wav
