A user complains that after returning from suspend-to-ram, he isn't able
to get any sound from his laptop until rebooting. I delayed reporting
this one because I once thought that it may be related to Pulseaudio or
some kind of mixer level problem but now I tried to suspect the kernel
and the drivers as well.
This is 18.104.22.168 with alsa-* 1.0.21a. I have dmesg and alsa-info outputs
before and after s2ram:
dmesg before s2ram:
alsa-info before s2ram:
dmesg after s2ram:
alsa-info after s2ram:
Note that a traceback is dumped in dmesg during resume. Maybe it will
give a clue about the problem, dunno.
And there's something like
hda_codec: invalid CONNECT_LIST verb 12:2100
in regular dmesg output, i wonder what does that mean too.
