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. Also, for verifying whether it's a driver PM problem, try the following: - Before and after suspend/resume, try to play without PA, PW or JACK but via ALSA native API, e.g. % aplay -Dplughw:XXX foo.wav where XXX is the card number like 0, 1, 2, corresponding to the device index appearing in /proc/asound/cards. I suppose this also results in the mono output? - Get alsa-info.sh outputs before and after the suspend/resume. - Check whether the problem persists with suspend-to-RAM and suspend-to-disk (hibernate). I assume you're dealing with the former, right? - 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. -- You are receiving this mail because: You are on the CC list for the bug.
