No sound in Firefox. All other browsers and applcaitons fine.

Posted

Hi all

I am open to suggestions other than reluctantly ditching the product after many years of being a happy user. I am currently back on IE11. Suddenly Firefox totally and utterly refuses to play any sounds from any web site. IE, Chrome and Edge all work fine. Here are the things tried so far. None have worked.

1. Start FF in Safe mode. 2. Set FF back to defaults. 3 Un-installed and re-installed with setting back to defaults. 4 Un-installed and re-installed audio drivers. 5. Un-installed and re-installed Adobe flash. 6. Removed Flash completely. Curiously all the sites I use, mainly YouTube, for videos still play Video fine. Albeit Firefox minus sound.

I really don't see how this can be anything other than a Firefox issue as everything else works fine. I really don't want to ditch it but a web browser without sound is pretty much useless really. Any sensible ideas other than ditching it are most welcome.

Many thanks in advance.

Tried 3,2,1 and 0 being careful to close it down fully after changing each time. Nothing I'm afraid. I will take a system image of my current setup and rebuild from scratch to nothing but FF after rebuilding and post the results.

Yes. That was about the first thing I tried. It's pretty basic and mostly irrelevant as this clearly a FF issue as everything else works fine. I can see FF come up in my sound mixer as I open it and it is not muted or turned down to zero.

Apologies. It transpires it is a problem with latest build of Windows 10 that affects only Firefox for web browsing thus far.
