background noise after upgrading to 19.04

[ground21]

Just after upgrading 18.10 to 19.04 I noticed there is some background noise from speakers. It's quiet but audible and really annoying. I have ALC1150 integrated on Z170 based motherboard if it matters.
I also noticed that the noise is gone for 5 seconds after emitting any sound (like playing a song/movie for a second or just clicking somewhere on volume bar so that system volume changes and audio feedback sound is played).
Please help me troubleshooting this.

I have the exact same issue. After upgrading from 18.10 to 19.04, my speakers make this clicking noise every second or so, but only when no sound is being played. It is really annoying and playing with alsamixer options did not fix it.

If you have intel hda, sounds like adding (or modifying if exists)

options snd-hda-intel power_save=0 power_save_controller=N

to /etc/modprobe.d/alsa-base.conf helps.

$ modinfo snd-hda-intel | grep power_save
parm:           power_save:Automatic power-saving timeout (in second, 0 = disable). (xint)
parm:           power_save_controller:Reset controller in power save mode. (bool)

This fixes it for me. Thanks!

I'm having audio feedback from speakers as well from time to time. I'm still using 18.04 LTS Motherboard is a AsRock AB350 Pro4. Sometimes it goes and goes and sometimes it goes away.

I have ALC1150. I have no idea if executing the command gives any reasonable output in my case, but here it is:

➜  ~ modinfo snd-hda-intel | grep power_save

Should I still modify /etc/modprobe.d/alsa-base.conf?


Update: I did modify the file and the issue seems to be gone. Thanks @0x656b694d

I just attempted this on Kubuntu 19.04. I recall this fix working without a problem in the past but now the powersaving click keeps happening even though it seems powersaving is disabled. Any ideas on what else could be causing this?

[linkchain]

Your solution worked for me, thank you!

[satya_461]

Thanks a lot! This worked for me! I am starting to hate linux for these reasons.. "too many basic things dont work either on upgrade or with devices".. Having hardtime to use airpods properly. ie. use airpods for mic.

I had this issue with Mint 20 and Ubuntu 20.04. This solution fixed the clicking, but now the machine won't shutdown properly. Any thoughts?
