It's because the runtime suspend is effective. Try to pass model=alc256-asus-aio option to snd-hda-intel module. Either boot with snd_hda_intel.model=alc256-asus-aio boot option or create a file (e.g. /etc/modprobe.d/hda.conf) containing options snd-hda-intel model=alc256-asus-aio If this works, we can put a static quirk entry for your device, too.
