When I installed Karmic K the Skype mike quit working and I was only able to get it working by upgrading to Skype 2.1. It worked fine for a month then the mike quit working again. I reinstalled Skype 2.0 but it didn't work--too many choices in sound device options all of which failed to work. So I then reinstalled 2.1 and it worked again. My guess is that Skype or something is resetting something on reboots. What is a pain in the *** about this is that reinstalling 2.1 didn't work. I had to install 2.0 then 2.1 to get it to work. Are they neglecting Linux by not fixing cheesy stuff like this? I would quit using Skype if it weren't for friends in foreign countries who use it.
