firefox not playing sound in youtube.com and flash sites

Posted

I have downloaded the beta 5 version and for some odd reason I cant play sounds anymore, even after I downgraded back to version 4 - youtube.com plays videos but no sound. I have all latest flash plugins installed. sound works on all other browsers

Chosen solution

See:

You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.
You can adjust the volume level for each application in that window, so make sure that Firefox is not muted or set at a low level.
You will only see the Firefox program in the Mixer if you are on a website that plays sound.
Also check the volume setting for the plugin-container process.

OH MY GOD: That was the solution. There is in fact a VOLUME MIXER for "Plugin Container For Firefox" and it was muted. No clue how that happened and I was not aware that there is a separate volume mixer for that. Thanks!
