no audio

Posted

Firefox 35.0.1; windows 7 Ultimate, 64-bit The only 'always activate' plug-ins are Acrobat and (either) Shockwave or Silverlight (not both).

FF web audio had been working. Now, video still works, but no sound - in particular, YouTube. However, audio does work fine if I open a FF 'private window' - same page, same FF; but there, it works. I had this same problem before, and it cleared after uninstalling/reinstalling Shockwave. This time, no luck with that. And, emphatically, I now see that Both Shockwave (16.0.0.305) and Silverlight plug-ins do the same thing. That seems to say that Shockwave is not the problem.

The Windows 'mixer' settings look fine.

Summary: - No audio from FF - ... except, if I open a 'private window'; Audio there works fine. - Same problem with either Shockwave or Silverlight plug-in - I have re-installed Shockwave, anyway.

Any suggestions would be appreciated.

What to do if Firefox won't play any sounds

Did you make sure that the sound isn't muted in the player or in the plugin-container process in the Windows Volume mixer?

Without meaning to be snippy, I think my post says that I'd tried these things ... to no avail.

That aside, the problem has spontaneously cleared, or at least gone into remission. Not from anything I did - a veritable miracle!

So, thanks.
