Tracking bug: The output sound may be garbled, "robotic" in some cases. The issue may occur randomly for some users. I can reproduce "robotic" sound on P1 gen 4 with the low-power mode settings and suspend/resume everytime. Affected hardware: Lenovo ThinkPad P1 gen 3, P1 gen 4, T14s gen 1, T14s gen 2 Reproducible: Always
Created attachment 1983826 [details] Lenovo P1 gen 3, performace power mode, kernel 6.4.9
Possible upstream fix: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=90219f1bd273055f1dc1d7bdc0965755b992c045 Discussed in https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/3390 and https://github.com/thesofproject/linux/issues/4482 . Thanks are going to Petr Stourac for the pipewire issue. A test kernel build for Fedora 38: https://koji.fedoraproject.org/koji/taskinfo?taskID=104978348 Please, report, if the issue was fixed with the test kernel. I cannot reproduce this issue on my machine with this kernel. Patch for 6.4 kernel: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2645/diffs?commit_id=3646d21c389ec7834fc09907787bf597342b7678 Patch for 6.5 kernel: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2646/diffs?commit_id=1a45c5fe1cb4f5478e0382351ec3e8744194fac9
The upstream fix 90219f1bd273055f1dc1d7bdc0965755b992c045 will be in the vanilla 6.5 kernel, too. No special handling for Fedora kernels is required.
There are quite a few people complaining about garbled audio on Fedora channels, e.g. here: https://discussion.fedoraproject.org/t/garbled-audio/87470 I asked them to test the patched kernel and provide feedback.
The https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2645 was merged. We should have this fix in the 6.4.12 Fedora kernel.
(In reply to Jaroslav Kysela from comment #2) > A test kernel build for Fedora 38: > https://koji.fedoraproject.org/koji/taskinfo?taskID=104978348 I wasn't able to reproduce the audio problem with this. On the other hand, on regular kernels, it happens completely randomly for me, so I don't have a reliable reproducer.
