I have audio on that port. I haven't tried yet reverting these
sound patches yet. demsg is filling up with these messages for
sure.


I just tried Linux 5.7-rc4 and it also has this problem. New in rc4 as
far as I can tell.

Then it's unlikely from the changes in sound/*, but I'd suspect rather
USB core side.  There is only one change for USB-audio driver and it's
a correction of USB device ID.



For what its worth not seeing this on 5.4.39-rc1 with the same set of
sound changes. I will start bisect on 5.6.11-rc1


I can't reproduce this problem on 5.7-rc1 and 5.6.11-rc1 after seeing
it once on both.

Tried powerdown vs reboot to see if it is tied to hardware init
sequence. Doesn't seem to make a difference. Oh well. I will
update if I see it again.

thanks,
