Alsamixer S-PDIF only for HDMI monitor connected by an NVIDIA GT 220, stuck on `nouveau` driver, speaker-test doesn't make sound
https://askubuntu.com/questions/1563555/alsamixer-s-pdif-only-for-hdmi-monitor-connected-by-an-nvidia-gt-220-stuck-on
Maybe I've no audio from my HDMI monitor because the card as alsamixer reports it, has 00 for everything and that everything is S-PDIF?
Someone else solved their "No audio from NVIDIA GPU, alsamixer only showing S/PDIF for HD" by:
disabling intel gpu and replacing noveau with Nvidia prop drivers.
But, my NVIDIA GT 220 is stuck using nouveau.
Also found: 6-year-old archlinux bug fixed by regression?
Maybe also relevant: occasional HDMI loss from my mixer if I wake up monitor from sleep. And speaker-test doesn't produce sound.

DVI-1? Hmm... People are saying "Some DVI-D sources use non-standard extensions to output HDMI signals including audio (e.g. ATI 3000-series and NVIDIA GTX 200-series)."
And well, "NVIDIA GTX 200-series" sure does describe my "NVIDIA GT 220"... Is that the problem???
