No sound for You Tube videos in Firefox after upgrade to 10.04
Hi all, I recently upgraded to Lucid 10.04 from Hardy 8.04, and since then I have no audio when watching You Tube videos in Firefox. I checked the sound preferences and I have sound in other applications, but not for You Tube.
Oddly enough, I get sound on You Tube just fine using the Chrome browser, but it's not my preferred browser and I'd really like to get it working under Firefox. In another forum, someone suggested doing a "sudo apt-get install alsamixergui," but that didn't help.
Is this some sort of Firefox bug? I googled the problem and others have reported it as such, but I cannot locate a fix. Anyone? Thanks in advance.
