[SOLVED] Distorted audio after one of the updates

So, after one of the updates I did this year, my audio started to be distorted. The way to fix it for the current session is to run `pulseaudio -k`. I need to do it every time I start the system.

Any idea how to diagnose it and fix persistently (not by running `pulseaudio -k` in autostart)?

My motherboard: Aorus Master x570 rev. 1.0 .

Re: [SOLVED] Distorted audio after one of the updates

Which update? When exactly? Was it recently - i.e. last week - with the pulseaudio 15 release or earlier which could be either one of the alsa-libs or an underlying kernel change. Like some time or version frame at least: https://bbs.archlinux.org/viewtopic.php?id=57855

Based on what we know I'd hazard a guess at snd-hda-intel powersaving which you could disable with a /etc/modprobe.d/disablePower.conf 

options snd-hda-intel power_save=0

.

If it's not that then you'll want to post more information, like 

aplay -l
pacmd list-sinks #Before and after killing pulse

It was few months ago, I don't remember when exactly, I just didn't have time to figure it out then.

It's not that one/didn't help unfortunately.

If it's any help this "distortion" sounds kind of like a feedback loop. It's the crackling sound of whatever should play repeated few times.

Actually, I didn't upgrade to pulseaudio 15 yet. I will do it right now and let you know if it fixed the issue.

Re: [SOLVED] Distorted audio after one of the updates

Ok, so it turns out that after installing the recent updates, with updated pulseaudio fixed the issue. So I marked it as fixed. Thanks for help! I didn't realize there was pulseaudio update recently smile .
