# How to fix crackling sound in PulseAudio

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% – Gorgo 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 ;) – Pretzel Jones May 11 '18 at 17:37
