So, recently, I installed Ubuntu karmic cleanly on my main desktop machine here at home, and I have really liked it. I even switched to KDE, and everything has been working better than it had been in GNOME. I tried setting up Skype the other day, and ran into an issue with the microphone. It turns out that since the new Skype uses PulseAudio, there’s a further configuration step that’s not so obvious. I found out here that you have to do the following:
sudo apt-get install pavucontrol pavucontrol
Then, go to the Input Devices tab, and unmute the sound (click the little speaker with a red X until the controls at the bottom are enabled). Then, change the Port setting until you can see the bars move when you tap the microphone. Then try Skype. This worked perfectly for me – it’s too bad it’s not connected to the KDE sound mixer, but oh well. Maybe in the future that will happen.
