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,
Mameka
