Description P D 2022-04-12 18:52:42 UTC

1. Please describe the problem:

A bug was reported here:

https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2272

The bug is caused by the latest 5.17.x kernels and causes some users (including me) to have audio stop working randomly in Fedora 36. A patch is available in the thread above, can you build the next kernels with the patch?

2. What is the Version-Release number of the kernel:

kernel-5.17.2-300.fc36.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

It worked in previous versions of Fedora, because previous versions didn't use 5.17 kernels.

An inclusion of the patch into the next Fedora 36 kernels would be greatly appreciated.

Comment 1 Justin M. Forbes 2022-04-12 20:25:27 UTC

I am aware of it. There is a work around for the moment, but I do plan to apply that patch as soon as it is queued. Unfortunately it is still not even in next.

Comment 2 Fedora Blocker Bugs Application 2022-04-13 11:06:48 UTC

Proposed as a Blocker and Freeze Exception for 36-final by Fedora user asciiwolf using the blocker tracking app because:

 This kernel issue causes audio cutouts, crackling and other audio issues for many users. The fix for this issue has already been merged in the sound.git tree (but was not yet backported to a stable 5.17).

Comment 3 František Zatloukal 2022-04-14 11:54:09 UTC

Discussed in ticket: https://pagure.io/fedora-qa/blocker-review/issue/751

The decision to classify this bug as an RejectedBlocker and AcceptedFreezeException was made:

"The issue has potential to affect large group of users, it doesn't violate the "The installed system must be able to play back sound with gstreamer-based applications." criterion".

Comment 4 Fedora Update System 2022-04-14 11:57:57 UTC

FEDORA-2022-013c7ab4d4 has been submitted as an update to Fedora 36. https://bodhi.fedoraproject.org/updates/FEDORA-2022-013c7ab4d4

Comment 5 Lukas Ruzicka 2022-04-14 13:33:35 UTC

The kernel seems to be working ok. I do not have an affected card here at the moment, so I cannot test if the error has been mitigated.

Comment 6 P D 2022-04-15 20:15:10 UTC

I had no audio cutouts since I installed the kernel, so it seems fine. Thanks! :)

Comment 7 Fedora Update System 2022-04-16 17:58:52 UTC

FEDORA-2022-013c7ab4d4 has been pushed to the Fedora 36 stable repository.
If problem still persists, please make note of it in this bug report.
