I was calling with my friend and suddenly he didn't hear me. I really don't understand why. I tried everything (I think). Restarted PC, changed some settings (as you said in help), tried change another microphone and nothing. One time, skype told me, that he can't connect with audio card or something like that. I would be very glad if you could help me some way.
