Audio stutters on Steam Deck across all audio outputs #1041

Closed RodoMa92 closed 6 months ago

RodoMa92 commented 6 months ago

Describe the bug

The audio seems to periodically stutters on the latest stable build on my Steam Deck LCD, and make the audio on bluetooth completely unusable since these causes a constant desync with the buds and therefore causes audio to go chipmunk mode. I thought initially that this was just a bug for bluetooth, but it's also present in the speakers, so I'm not sure if it's just a platform stutter caused by the new 6.8 kernel that has been merged or if it's just a pipewire bug. I've opened an equivalent bug report for pipewire here: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3981 I still need to update it with the fact that the whole platform causes stuttering.

I thought that the new BIOS from Valve that enables CPPC was a possible cause, but after downgrading it back to 121 that was fine for the last four months I can reproduce the issue with no effort, so that's not the source of the problem.

What did you expect to happen?

Audio plays normally without a stutter every 10 seconds using speakers or having desync issues on bluetooth.

Fixed it, the problem was coming out from my setup with Timidity server, it was causing pipewire stutters for some reason. Switching directly to fluidsynth server fixed it.
