Flash has no sound
Using Firefox 10, now 11, under OS X Lion, I have no sound in flash videos and animations. I have sound in flash videos and animations under Chrome & Safari. I have sound in all other apps. I have sound in Firefox when the video or animation is not flash (HTML 5, for example.)
Additional System Details
- Shockwave Flash 11.1 r102
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:11.0) Gecko/20100101 Firefox/11.0
I have checked all the settings suggested in the No Sound with Flash article in the Firefox knowledge base. This includes checking global storage, making sure third party sites can store information for embedded videos, clearing the cache, allowing pop ups. I've also checked the Midi set up to make sure sound is correctly set at 44,000 khz. I have completely uninstalled and reinstalled Firefox. I have completely uninstalled and reinstalled Flash. I have rolled back to an older version of Flash. I have removed all plug ins and extensions except for Shockwave Flash. Nothing has worked.

I'm having the same problem with Firefox 11 and Flash 126.96.36.199 on Windows 7. Flash works normally in both Chrome and IE, but I get no sound in Firefox. HTML5 videos play normally. I've tried all the above fixes with no luck.
I should add that, unlike the original poster, the problem started for me in Firefox 11, not 10. And as far as I can tell, it didn't happen following any Firefox or add-on updates.
I found this just now:
It fits the question, and I had the same problem. Their temporary solution for windows 7 was to lower the bitrate to 44100 KHz and that solved the problem for me. :) Figured I'd share.
