Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.
These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)
Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies
I can't find any more suggestions on the internet, so any further suggestions welcome!
