RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Tuomo Soini 2023-07-28 18:37:35 UTC
Description of problem:

After pipewire was updated to 0.3.67 there has been audio distortion.

This happens once in few days. And every time if you change from laptop speakers to bluetooth audio or other way around, distrortion vanishes.

Verified that distortion completely vanishes when pipewire\* are downgraded to previous versions of packages (0.3.47-3.el9_2).

This problem was identified on Lenovo Thinkpad Carbon X1 gen 9.

I have a similar distortion issue, which happens when starting a new audio stream. Either through VLC (online radio), or in browser at Spotify.
Sometimes it works fine for hours, sometimes it breaks every 3-4th song.

Once audio got distorted, when I closed the audio mixer.
Seems to me, its happening 

The solution is to change the audio profile from Audio Mixer->Configuration->Profile. I change from 'Play HiFi quality Music' to 'Pro Audio' or 'Off', and back to 'Play HiFi quality Music'. Sometimes I have to do it twice to fix audio.

Fedora 38/XFCE with Pipewire 0.3.76, on Lenovo Thnikpad T15 Gen2 (i7-1165G7).

Comment 2 Kaloyan Petrov 2023-08-03 08:31:00 UTC
Distortion appears almost every time, if I seek forward multiple times.
For example in a YouTube video, with the arrow keys.

You should create separate fedora bug. This bug is about pipewire problems in centos stream 9, Not fedora.

Comment 4 Dmitry Tantsur 2023-08-23 07:12:32 UTC
I've filed a Fedora bug: https://bugzilla.redhat.com/show_bug.cgi?id=2233729

Comment 5 Kaloyan Petrov 2023-09-01 10:35:44 UTC
I think its fixed now. Haven't seen it for a while. Tried to reproduced multiple times, but no bug now :)
Running latest updated versions of software:
firefox-117.0-1.fc38.x86_64
pipewire-0.3.79-1.fc38.x86_64
kernel-core-6.4.13-200.fc38.x86_64
