Ubuntu Sudden Sound Problem

view full story

http://www.linuxquestions.org – Hi folks, In the last week I have been noticing sound issues. Today my sound stopped working all together. I have a dual boot system: Windows XP and Ubuntu 8.10. The sound works fine under XP. My understanding is that there are problems with PulseAudio. Ive checked all the obvious things such as "mute" etc. My guess would be a corrupted sound card driver, but im not sure of the best way to remove it and reinstall it. (HowTos)
