Firefox (and firefox only) does not play audio of any kind on any device or site

more options

Good morning. As the title suggests, Firefox suddenly doesn't work after a windows 10 update a few days ago. The videos play, but the audio doesn't work. Microsoft Edge plays audio smoothly.

I tried to: - Clean the cache - Clean cookies - Check permissions for sites (automatically play Audio / Video etc.) - Restore Mozilla - Restart PC - Uninstall Mozilla - Check in the volume mixer that Mozilla was not muted - Check that the tab wasn´t muted. - Check in Settings > Sound to see that Mozilla is present among the various programs used by the Sound Card - Checked if Mozilla played with another account - Used Troubleshooting mode

I don´t know what else to do, I don´t recall touching anything but Bluetooth Settings from time to time to reconnect my Headphones.
