Firefox 3.6.8 just now on Ubuntu 9.10, but happens on 8.04-10.04 Ubuntu with related older Firefox versions.

Problem is probably related to Youtube/Flash problems, but something gets stuck in Firefox. I can close the main instance of Firefox, but looking in 'top' I can still find processes running for Firefox (sometimes if I try to restart Firefox I will get a note that Firefox is already running). If I kill those 'runaway processes' then restart Firefox I have Youtube/etc sound back.

When this happens all programs on the computer cannot produce sound. When processes killed then sound works all around.

I was able to fix this problem on my computer in Windows 7. Try going to start/control panel/programs and then uninstall the flash plugin - then start browser again go to a flash video and when prompted install plugin again. This worked well for me let me know how everyone else makes out.
