Thanks. This is the same issue as bug #106957, only that one was for=
 AMD cards
and yours is an Nvidia. It was fixed by commit 57cb54e53bdd ("ALSA: hd=
a - Force
to link down at runtime suspend on ATI/AMD HDMI").

If you add "codec->link_down_at_suspend =3D 1;" to patch_nvhdm=
i() in
sound/pci/hda/patch_hdmi.c, the issue may go away.

The only question is whether your card's revision_id is listed in
snd_hda_id_hdmi[] such that patch_nvhdmi() is executed for your card. What =
does
"cat /sys/bus/pci/devices/0000:01:00.1/hdaudioC1D0/revision_id" s=
ay?
