Excerpts from David Rosenstrauch's message of julho 6, 2023 2:05 pm: > 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. > You can try to use the Arch Linux Archive to pinpoint around when this started happening, which might help you narrow it down. > 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).

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