Hi, On my debian stable firefox 75 the sound stopped working.
Another user does have sound on stock firefox. I can not go back to stock firefox, my profile of firefox 75 can not be loaded any longer. 7 Chapters of troubleshooting pulseaudio did not help me in 4 hours: https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting Another thing from this guy Pottering does not give any hint: journalctl -f journalctl -f | grep pulseaudio nothing pulsemixer does seem to be alright: firefox: AudioStream is showing up, I can select it, and set volume (but no sound). but: $ pactl list sink-inputs no output at all $ pacmd list-sink-inputs 0 sink input(s) available. I am left clueless. (no timidity here installed. alsamixer shows the pulseaudio interface, unmuted) [ I hate pulseaudio since when I had a linux terminal server project LAN. In those days pulseaudio fucked up all LAN audio playing. ] Waterfox and Palemoon browsers both play audio well. Hope someone can give a hint Thanks 4 reading
