[alsa-devel] The SPDIF light on the Eurocom Q6 (Clevo P95xER-series) is always on
Hello there,
As stated in the subject, the SPDIF light on the machine is always on, and this is only when I boot into Linux.
Output from alsa-info: http://www.alsa-project.org/db/?f=29b57d6465130b92dd70360150aad528cfb85f92
I can get both the internal audio + headphone jack to work by editing /usr/share/pulseaudio/alsa-mixer/paths/iec958-stereo-output.conf and adding:
[General] description = Headphones + Digital Output (S/PDIF)
Infront of the
[Element IEC958] switch = mute
section.
Other specifics:
lsb_release -a :
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04 LTS Release: 18.04 Codename: bionic
pulseaudio --version :
pulseaudio 11.1
aplay --version : aplay: version 1.1.3 by Jaroslav Kysela perex@perex.cz

Try to run like: amixer -c0 cset iface=mixer,name='IEC958 Playback Switch',index=16 off
Does this turn off the SPDIF light?

Hello Takashi,
Running amixer -c0 cset iface=mixer,name='IEC958 Playback Switch',index=16 off turns off the SPDIF light.
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?
Also, does turning off the SPDIF light as shown above disable SDPIF output?
Regards,
Dennis.

And is the SPDIF light turned on again by some other action?

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.
Takashi
Thank you for the clarification.
