After a lot of time (and negative votes) I decided to install pulseaudio, since sound in my 9.10 system was not working properly. And I must admit that solved almost all of my sound problems. All is left is a small one. My mic works perfectly. I tested it under audacity. But when it comes to skype I can't get it working. In skype preferences, all my sound devices options is "PulseAudio Server (local)". I have no other option, but mic still doesn't work.The thing now is that I don't know what could I search for solving this.
Thanx in advance for any help.
