No sound - Intel HDA SOF driver and Nvidia HDMI

No sound - Intel HDA SOF driver and Nvidia HDMI

[Mameka via]

I installed Guix System on my ASUS TuF Gaming 705 GM notebook. There is an Intel / Nvidia Optimus graphics card. The sound modules are Intel HDA and Nvidia HDMI. After a normal boot the Nvidia HDMI is activated and I don't hear any sound out of the speakers. Only the "dummy driver" is loaded.
If I plugin an USB sound card this works fine. But I like to use the internal sound card.

Some logs:

Sorry for the bad format. It was a mistake.

cat /proc/asound/card*/codec* | grep Codec
Codec: Nvidia GPU 84 HDMI/DP 

lspci | grep -i audio
00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
01:00.1 Audio device: NVIDIA Corporation GP106 High Definition Audio Controller (rev a1)


I tried Trisquel 9 before Guix and there the sound was working
fine. Trisquel uses the Libre Kernel as well, so I hope that Guix System can do it also. I tried to
blacklist the snd_hda_intel in the /etc/config.scm
(use-modules (gnu)) 
(use-service-modules desktop networking ssh xorg) 
(use-modules (gnu services virtualization)) 
[...] 
(kernel-arguments '("modprobe.blacklist=nouveau,snd_hda_intel,snd-hda-intel")) 
[...] 
(supplementary-groups '("wheel" "netdev" "audio" "video" "libvirt" "kvm"))) 
[...] 
Unfortunately this does not work. I get no sound.
Blacklisting the snd_hda_intel worked in Slackware and Debian. 

Any advice is welcome. 
Kind regards,

Hello Mameka,

This seems correct.

I cannot be of much help, but

you could check with lsmod if
snd_hda_intel really is disabled and

you could check with pavucontrol
if it displays any sound and

you could check with alsamixer if sound is muted.

Best of luck!

Florian

You could set a different Linux-libre kernel version in your operating
system declaration, e.g.
(kernel (@ (gnu packages linux) linux-libre-5.10))
or (kernel (@ (gnu packages linux) linux-libre-5.4)).

If you don’t mind recompiling your kernel: Searching in my

/run/current-system/kernel/.config

reveals a few occurrences of HDMI in the kernel configuration.  You
could set in your operating system declaration:

(kernel
 ((@@ (gnu packages linux) make-linux-libre*)
  (@@ (gnu packages linux) linux-libre-5.14-version)
  (@@ (gnu packages linux) linux-libre-5.14-gnu-revision)
  (@@ (gnu packages linux) linux-libre-5.14-source)
  '("x86_64-linux")
  #:configuration-file (@@ (gnu packages linux) kernel-config)
  #:extra-options
  (append
   '(("CONFIG_SND_HDA_INTEL" . #f))
   (@@ (gnu packages linux) %default-extra-linux-options))))

or similar, but this may need to be adapted with future Guix versions.
If it works at all.

Also I suppose you have exactly the same hardware setup as with
Trisquel or Debian.  For example, I remember something advertised as
an HDMI cable but it could not carry sound.

Florian
