I just installed Ubuntu 10.10 and I have updated my system and installed my video drivers however the sound keeps muting especially while watching youtube videos or watching an AVI file. The sound icon goes red and it stops working. I have never had this problem with any of the previous Ubuntu distros and I cant seem to fix it. I have tried changing the audio settings under the hardware tab with no success and I have tried finding update for pulse audio with no luck. Any help would be greatly appreciated, I really want to give Ubuntu 10.10 a try without having to go back to 8.10 or 9.10 just have sound working.
