I did a system upgrade a few days ago, that I had been delaying for a few weeks. Probably nearly 300 packages got upgraded, including the kernel, pipewire, etc. Since then, I keep having a recurrent problem with audio distortion, which I haven't been able to pin down a cause for.

To start out, the audio is fine, using my ear bug headphones with my laptop's audio jack. Then, after a few minutes, suddenly audio distortion kicks in. It happens when using both streaming music (audacious) as well as voice (zoom). I seem to be able to "clear it out" by temporarily turning off my current audio profile in the pavucontrol app, and then re-enabling it. But the distortion just returns again after a few minutes. I've tried different headphones, switching to laptop speakers, etc., but I still get the distortion.

I haven't been able to figure out which component or configuration setting is causing it, and haven't seen any currently open bug reports or any mentions in the Arch forums or here on the mailing list that describe anything similar. Has anyone else been experiencing anything like this and/or know what the cause or solution might be?

My laptop configuration is: * linux 6.4.1.arch2-1 * pipewire 1:0.3.72-1 (with pipewire-alsa, pipewire-audio, and pipewire-pulse also installed) * wireplumber 0.4.14-1 * audio hardware: "Tiger Lake-LP Smart Sound Technology Audio Controller Speaker + Headphones" * selected audio profile: "Play HiFi quality music"

Thanks,

DR

zoom

Hi,

I can't comment on {aur,chaotic-aur}/zoom. At the peak of the pandemic, I took part in some training courses, some of which were conducted via Zoom. I didn't do this with my Arch Linux PC, but with an iPad Pro. At first I refused to install the app and tried Zoom from different web browsers. This was a total disaster when it came to audio. I ended up using the app and although it worked better, it was still no fun in terms of audio. It wasn't ok with the iPad's internal audio thingy, let alone a Focusrite Scarlett 18i20 2nd generation. This was without streaming music at the same time. It made my hair stand on end when I read Zoom related to audio issues.

If you use Zoom by a web browser, try whatever is provided by the AUR or the chaotic-aur repository.

Regards, Ralf

You can try to use the Arch Linux Archive to pinpoint around when this started happening, which might help you narrow it down.

By turning off I assume you use pavucontrol to set it to off.

Try using the pro audio profile. Also, make sure you don't have any pipewire/wireplumber configuration that could be causing issues.
