Thanks. This is the same issue as <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - GPU runtime suspend broken since 4.17" href="show_bug.cgi?id=106957">bug #106957</a>, only that one was for AMD cards and yours is an Nvidia. It was fixed by commit 57cb54e53bdd ("ALSA: hda - Force to link down at runtime suspend on ATI/AMD HDMI"). If you add "codec->link_down_at_suspend = 1;" to patch_nvhdmi() 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" say?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
