Wanted to share a quick solution I found on No Sound in Firefox

I had trouble with sound in FireFox. No matter what Windows 7 had for Firefox’s volume, no sound would come out. I would even see the green indication of the sound go up and come down with audio coming out of FireFox.

I did find the solution in an article by zarindenatrose.My first give away was that if I renamed firefox.exe to FixFirefox.exe (anything besides firefox.exe) then FireFox played sounds. Clearly there was a problem in Windows 7′s registry. That article described how to delete the problem registry entries to restore Windows 7 (or Vista as the article says) concept of Firefox’s volume. In a later update to his article, he said some people had to delete multiple entries. I did too.

In my search other users had issue with Adobe Flash player but thought the issue was Firefox. If my suggested fix didn’t work, then perhaps your problem is with Adobe Flash Player.

I’m glad that zarindenatrose took the time to make that article. So I’m taking the time to say thank you and add a blog entry.
