Similar to commit 9479e75fca37 ("ALSA: hda: Keep the controller initialization even if no codecs found"), when codec probe fails, it doesn't enable runtime suspend, and can prevent graphics card from getting powered down: [ 4.280991] snd_hda_intel 0000:01:00.1: no codecs initialized $ cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status active So mark there's no codec and continue probing to let runtime PM to work.
