I have been experiencing a crackling sound after enabling the PulseAudio Equalizer.

  • Already had load-module module-udev-detect in my default.pa. Added tsched=0 but crackling still present if the volume is >100% – Davide Dec 6 '17 at 22:25

(the following answer was provided by OP himself, but was originally included in the question body.)

Searching for a solution I found one within the Arch wiki and I wanted to share it with everyone. This typically affects machines with Intel sound chips.

sudo -i scratch-text-editor /etc/pulse/default.pa

Add line below to end of file, then save

load-module module-udev-detect tsched=0

Then type in terminal:

pulseaudio -k
pulseaudio --start

I've added this to the elC - elementary Combobulator project as well.

  • your code is miswritten it should be SCRATCH instead of sratch. – hmd May 11 '18 at 7:23
  • That's why it's always suggested you type commands manually rather than copy paste ;) – Sean Patterson May 11 '18 at 17:37
