Sound Cracking and Popping Ubuntu 19.04

Question

I have spent a lot of time searching the web for an solution but nothing seems to work. I tried these fixes

Static and crackling sound coming from speakers in 19.04

Cracking and popping sound from left side of headphone on Front Left/Right sound test

and the pulse-audio fix but nothing worked.

My Speakers just randomly crack and make noises when doing nothing and sometimes while playing back audio. I haven't had that Problem before and when i boot into windows everything is fine. So i can rule out a Hardware problem.

I got the Z370 AORUS Gaming 5 (rev. 1.0) with the Realtek® ALC1220 codec. Connected is an 5.1 Surround system made by Logitech.

The Problem was already there in 18.04 and Upgrading to 19 did nothing to fix it.

I just tried connecting and then switching to my external soundblaster card but staying connected to the mobo headers and the noises continues

Solution

I had the same problem on Ubuntu 18.04 - cracking sound from left speaker that occurs mainly before the playback of video/audio. This solution from James Kelly works for me:

if your distro uses alsa you should be able to fix the issue directly by modifying the following conf file: /etc/modprobe.d/alsa-base.conf

Open file in console using:

sudo nano /etc/modprobe.d/alsa-base.conf

Add the following line to the end of the file:

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

Hit Ctrl-S then Ctrl-X

And you have to restart the maschine after that (or just alsa).
