I added "HDA_CODEC_ENTRY(0x10de0403, "GPU 0403 HDMI/DP", patch_nvhdmi)" to snd_hda_id_hdmi[] (PCI ID of my Nvidia HDA wasn't there) and "codec->link_down_at_suspend = 1;" to patch_nvhdmi(). With those changes dGPU and HDA suspended normally (after echoing "auto" to HDA control file), so I think that this is definiteley the right track!</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
