I have Skype 184.108.40.206 for Linux, and whenever I make a SkypeOut call to a phone, sometimes the microphone works, and sometimes it doesn't. It's completely random, and it's about 50% either way. By that I mean there's a 50% chance of the mic working every time you make a call, so restarting the program doesn't affect anything.
Every other application that uses the microphone works fine. My guess would be that Skype is switching between microphone configurations for some reason. It's very hard to search for this problem, of course, because there's no consistent way to describe it.
I'm running Ubuntu 9.04.
I have a Sound Blaster Live 5.1 running the emu10k1 driver.
Skype's "Sound In" is configured as: SB Live 5.1 SB0220 (hw:Live,2)
I've also killed pulseaudio, which has been known to cause sound problems, and it didn't help.
Has anyone else encountered this problem?
Here's the cross-post to the Skype forum.
