Firefox will show that audio is "playing" but no sound will come out, unless I connect a bluetooth speaker or headphones. Solutions tried (and failed): 1. uninstalling all audio drivers 2. checking if it's a problem with my computer (it's not, every other application plays sound) 3. enabling cookies 4. allowing autoplay video and audio 5. completely uninstalling and clean installing firefox again 6. turning off bluetooth to see if the pairing is the problem 7. cleared cache 8. turned off any adblock and/or extensions whatsoever 9. allowed drm content to play 10. allowed pop-ups 11. reset settings preferences any help or input is appreciated. Thank you!
