This happened again to me today. I was in a MSTeams chat session (standalone app, not the web version) and opened a webpage in Firefox that garbled the sound of the meeting in progress. I noticed that when it happened that in the system audio mixer/volume control manager, there was suddenly a lot of entries for "speech-dispatcher" that previously weren't there. And this was also reflected in the list from the `ps` command:
188672 0.0 0.0 450364 8304 ? Sl 11:50 0:00 /usr/lib/speech-dispatcher-modules/sd_espeak-ng /etc/speech-dispatcher/modules/espeak-ng.conf 188678 0.0 0.0 360052 5660 ?

Sl 11:50 0:00 /usr/lib/speech-dispatcher-modules/sd_generic /etc/speech-dispatcher/modules/espeak-generic.conf 188687 0.0 0.0 159724 2236 ? Ssl 11:50 0:00 /usr/bin/speech-dispatcher --spawn --communication-method unix_socket --socket-path /run/user/1000/speech-dispatcher/speechd.sock Without touching the webpage or Firefox, I used the command-line to kill the one that looked to be the main speech-dispatcher process, which was the 188687 process ID in this case (which also closed the other speech-dispatcher processes). And immediately, the audio cleared up and I was able to continue browsing the webpage while the MSTeams meeting continued. This makes me wonder if the problem is actually Firefox or if it's speech-dispatcher -- or perhaps it's the data that Firefox is streaming to speech-dispatcher?? Like the others in this thread, I have experimented with the speech settings in Firefox to no avail. If there's a magic setting to disable it, I haven't found it. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1906741 Title: Firefox sometimes causes garbled audio Status in firefox package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Opening certain applications/websites at the same time as Firefox causes the audio to become garbled. The audio sounds distorted with an echo. Certain actions are guaranteed to cause this, but it can also happening when only running instances of Firefox. I've been able to consistently cause this by launching Zoom from a link within Firefox. This does not occur when using Chrome. The only way to fix the issue is to shut down all audio-related programs.
