A month ago I installed 20.04 from scratch after using 16.04 for severl years and I noticed a weird sound coming from my speakers. It started right from the very beginning after I installed clean 20.04. I've attached the sound below. It happens whenever there is no sound coming out from the speakers, that is when I don't listen any music, etc. When I stop the sound, it starts again after around 5 seconds. I am using these GX Gaming speakers https://www.amazon.co.uk/Genius-SW-G2-1-1250-Channel-Speaker/dp/B007IZRQES.

  • As I said, I didn't have this problem on Ubuntu 16.04 so I don't know how this would be a hardware issue. – jedi Mar 14 '22 at 20:44

    What is the audio card? Maybe power_save issue like https://askubuntu.com/questions/1230833/annoying-click-popping-sound-on-ubuntu-20-04 – Andrew Lowther Mar 14 '22 at 21:35
  • @AndrewLowther I updated my answer to show my audio card. Your link worked for me. – jedi Mar 14 '22 at 21:57

The fix for this issue is to disable power save on the card. The link suggested by Andrew Lowther above provides the solution.

Power save is good! Try to avoid disabling it ;) There is a probable alternate solution, from https://askubuntu.com/a/1399239/817790 that worked instantly for me. (probably improved audio quality, too)

Kernel version 5.13.0-37. (Use uname -a to check your kernel version.)

sudo nano /etc/pulse/daemon.conf

Find the lines starting with

; default-sample-rate
; alternate-sample-rate

Remove the ; and change the values to 48000 so it looks like this:

default-sample-rate = 48000
alternate-sample-rate = 48000

Save the file, then restart pulse audio with

pulseaudio -k

Adding to the solution posted by simlei, you can also try to change the buffer size by adjusting these settings to something like this:

default-fragments = 3
default-fragment-size-msec = 5

Where the effective latency is the product of the two.

The third solution (and I know you said your problems started right after you installed Ubuntu 20.04) is to plug the speakers into a separate power outlet (if you're using a power strip), so as to make sure they're not picking up any static from outside sources. (I had a really serious problem with this).
