Hello,
I recently installed guix onto a newly acquired laptopn (alienware x14 r1). Install went smooth, but I did notice that audio (microphone, speakers) only works if I have usb-c headphones plugged in.
With out headphones connected, the audio output in gnome settings just says “dummy output”, and there’s no input device specified for the microphone. If I connect usb-c headphones the output and input fields now have valid options. I can also connect bluetooth devices and their output and input options show up in the appropriate fields in gnome settings.
So audio capability is their, just not always active. I don’t know if this is a gnome thing, or if I need to tweak my guix config. I searched around and found the guix sound and audio services so maybe I need to add some of that into my config? Though my prior laptop audio stuff worked without having to tweak any of that so I’m not sure.
For reference my config is (how cool is it that someone can just paste their system config somewhere. Ahh the power of declarative configuration):

(use-modules (gnu packages dns))
