Hello Takashi,
Running amixer -c0 cset iface=mixer,name='IEC958 Playback Switch',index=16 off turns off the SPDIF light.
And is the SPDIF light turned on again by some other action?
If I may ask, with this model, the primary sound card shows up as the ALC1120:
cat /proc/asound/car*/co* | grep Codec Codec: Realtek ALC1220 Codec: Intel Kabylake HDMI Codec: Nvidia GPU 83 HDMI/DP
Would a model override via:
options snd-hda-intel model={model_name}
in /etc/modprobe.d/alsa-base.conf using a model name from https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree... be applied to work around the issue above?
No, this has nothing to do with the model. It's only the question who turned on the mixer.
Also, does turning off the SPDIF light as shown above disable SDPIF output?
Yes.
