I added "HDA_CODEC_ENTRY(0x10de0403, "GPU 0403 HDMI/DP", pat=
ch_nvhdmi)" to
snd_hda_id_hdmi[] (PCI ID of my Nvidia HDA wasn't there) and
"codec->link_down_at_suspend =3D 1;" to patch_nvhdmi(). With t=
hose changes dGPU
and HDA suspended normally (after echoing "auto" to HDA control f=
ile), so I
think that this is definiteley the right track!
