No audio output device

[Gabor Gero]

Hello,

I'm struggling to get audio working on Guix. I am on a laptop, but the 
system detects neither the built-in speakers nor any external output 
device I attach to it. I have installed pipewire-home-service with the 
default configuration but it hasn't helped. What can I try? I am on 
commit d1e9e23.
