[Bug 1191247] New: audio goes to mono after waking up from sleep
https://bugzilla.suse.com/show_bug.cgi?id=1191247 Bug ID: 1191247 Summary: audio goes to mono after waking up from sleep Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: 64bit OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: pandre.x@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- hey everybody. I got this issue with regards to the audio coming from my USB sound card (Audient iD14): every time I put the pc on sleep and wake it up, every single source of audio goes to mono and I can hear the music/sounds coming just from one of my two speakers. I did update to PipeWire, however the issue continues as it was with PulseAudio or Jack. To fix that I can either plug my usb sound card off and plug back in or restart the pc.

Thanks for quick testing.
Then could you load alsa-info.sh output from the patched kernel after suspend/resume? Run the script with --no-upload, and use Bugzilla attachment.
Thank you. Sorry but I have no idea how to run this script. where is located? so sorry, I'm not that expert :D
It's /usr/sbin/alsa-info.sh included in alsa-utils package. It should have been already installed. Just run it as root with --no-upload option, and attach the generated file to Bugzilla (don't paste, it's big).
- Check whether the problem persists with suspend-to-RAM and suspend-to-disk (hibernate). I assume you're dealing with the former, right?
Hibernate it doesn't work on my PC (maybe because I don't have a swap partition?).
Right, hibernate works only with a swap (or other dedicated) partition.
- Last but not least, check whether re-loading the driver fixes the problem without re-plugging. You might need to go out of desktop session once, unload snd-usb-audio module and re-load snd-usb-audio module on Linux console.
Again, so sorry but I don't know how to stop and re-load this module.
OK, then to make things easier: - Try to boot with a boot option "3" This will boot to Linux console without GUI - Login there, plug USB-audio device, test directly via aplay % aplay -Dplughw:XXX foo.wav as mentioned in the above. - Do suspend/resume % systemctl suspend - Check again aplay and confirm the mono output - Unload / reload the module % sudo modprobe -r snd-usb-audio % sudo modprobe snd-usb-audio - Test aplay again -- You are receiving this mail because: You are the assignee for the bug.

The next step is try to adjust the mixer values manually after suspend/resume and see whether it influences on the behavior.
Unfortunately the alsactl contents are empty in alsa-info.sh outputs by some reason. Could you run the following as root, and attach to Bugzilla?
alsactl -f /tmp/alsactl.out store
Hi, I forgot to attach the alsactl.out I was able to generate after creating 60-usb-audio.conf Hopefully it will says why my right channel is lower in volume. -- You are receiving this mail because: You are the assignee for the bug.
