Linux Firefox broken sound

 https://tqdev.com/2021-firefox-ubuntu-crackling-sound

 

 

Fix 1:

Go to about:config in Firefox and search for "media.webspeech.synth.enabled" and set it to "false" (double clicking on the entry should do it) then close Firefox. Don't forget to restart Firefox.

Fix 2:

It seems related to speech-dispatcher (some text-to-speech utility), so you can try:

killall speech-dispatcher

If the sound comes back to normal you can remove it completely (if you don't need it) with:

sudo apt remove speech-dispatcher

Don't forget to restart Firefox.
