So I have been having this issue for a while now, and I have tried everything to fix it on my own.

My issue is sometimes you-tube videos will play about 1-2 sec of sound then stop, the video will buff all the way out and I can watch it but no sound will come from it. Once it happens if I try to watch another video they will all have no sound, but if i start up itunes it will still play music, so it's not my PC.

Once I close Firefox and reopen it 80% of the time it will play sound on the same video, the other 20% of times it will play 1-2secoinds of sound again and quit playing sound, if I restart fire fox again it will play just fine. Also I do not seem to get this issue with internet explore.

Stuff I have done. Check for updates for my video/sound cards. Uninstalled/installed flash 3 times even downloads the Adobe Flash player uninstaller, then reinstalled flash again. Unchecked enable hardware acceleration, in the Adobe Flash setting.

My setup Firefox 3.6.13 Windows 7 64bit ATI HD radeon HD 4350 video card. I have my PC connected to my TV, sound/video is carried with a HDMI cable from my video card.

Did you check the settings for Firefox in the Volume Mixer?

Thanks for the reply, but I have already read most of that, and the answer I get is just to uninstall flash and reinstall. It starting to really suck because the only answer I can find is that.

I'm really not thinking it is flash because everything works in IE, my next step is to uninstall Firefox and reinstall it.
