Where do I find answers? I have reported this problem 4 times before. I have no audio with FF 4.0.1 running on Win 7 Ult. No problem with any other browser nor any other app.

Try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your add-ons is the culprit.

Thanks to those who offered a solution. I finally found the answer and here are the steps to solve the no audio problem.

1- Make sure that QuickTime is up-to-date and working properly 2- Open a URL running audio 3- Open the Volume Mixer (Speaker icon on bottom right corner on screen) 4- Make sure none of the choices are muted and that volume is set at a reasonable level.
