I disabled PulseAudio to be able to use my microphone for Skype, and now the volume controls don't work, which I understand, is a common problem.
I read that somebody fixed their Skype microphone by going to
system setting > multimedia > phonon > audio recording > prefer webcam microphone.
I'd like to try that, but I think I need to enable PulseAudio again. How do I do that?
I used the following guide on Skype's support pages to disable PulseAudio: Can I change the sound system used by Skype for Linux?
