[Bug 1739310] Re: Sound crackling in Ubuntu 16.04

[Robin Preiss]

I have the same issue on Xubuntu 18.04 and Debian Stretch. It occurs on
a fresh install while watching a video in Firefox. Restarting Pulseaudio
does fix the issue for me as well.

I observed that when the problem occurs, I can see multiple instances of
speech-dispatcher in Pavucontrol. Whenever I select a different output
device for all of them, the crackling disappears. If one of them has the
same output device selected as Firefox, the crackling comes back.

I could fix the issue by uncommenting the last line (DisableAutoSpawn)
in /etc/speech-dispatcher/speechd.conf.

I hope it might help.

My system:
Xubuntu 18.04
CPU: Intel i3-4160
Motherboard: Gigabyte H97-D3HM
GPU: Nvidia GTX 1060 3GB
