I've had problems with Skype for a bit, but managed to fix some of them (using Skype from the repos to make it work with Pulseaudio, fixing cracking sounds as described in a blog post on itbubbles).
Now I have a rather odd problem: I have different Ubuntu accounts for work and private, and Skype works fine in my work account, but in my private user account, the microphone doesn't work. I think I did the last Skype reinstallation on the work account.
The microphone works well in other apps, but only silence in Skype (although I can hear the other side just fine). But the Skype recording does seem to transmit system sounds (Skype notification sounds are recorded/transmitted).
I tried with a clean Skype profile (dumping the
~/.Skype directory), but no effect. I'm on XUbuntu 13.10, Skype 188.8.131.52.
What settings could be saved user-specifically? Access right issues? User-specific audio settings?
