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).

Done, I've attached both pre-sleep and post-sleep alsa-info.sh output

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

done, I can confirm it sound in mono. Once I try to reboot the usb module, it gives me "Device or resource busy". Please see screenshot attached "rebooting usb module". Thanks! -- You are receiving this mail because: You are on the CC list for the bug.
