From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Kubuntu 24.04 - Sound output jumps really high after about 5-10 minutes (self.linux)

I am running Kubuntu 24.04 and I have an issue I can't seem to figure out. I am using my onboard intel sound card with optical output. The sound is great, but every 5-10 minutes the sound turns into a loud mess of noise (its hard to describe, kinda like static).

After some tinkering I have determined that what is happening is the sound card is outputting volume much higher than expected. If I turn the volume down to just above mute, I can hear the sound normally its just badly over-driven. The volume levels in my mixer look fine, so I'm really confused. If I am in firefox, muting the sound for about 10 seconds will resolve the issue when I unmute, but if I am playing a game, I have to quit to fix it.

I've been searching the web for several days and found a couple possible solutions that involve disabling snd_hda_intel powersaving modes via module options. But they have had no effect.

I also found one article with a nearly exact description of my issue on Archlinux forums, but the guy never figured it out, it just started working after an update one day.

Is there anything else I can try to fix this?

Try reinstalling pipewire or pulseaudio

I just installed last week, could that really be messed up already?

You can always try, it fixed my issue when I couldn't hear anything on my laptop yesterday(I run pop os)

So long-term it did not resolve my issue. I also tried updating pipewire using PPA repositories. still have the issue.
