Hi,
thanks for your thoughts.

1.
I don´t have "guix home"

so. should I include this in my config.scm:
> "(service home-pipewire-service-type)"

or > "(service pipewire-service-type)"
because "home-pipewire" is for "guix home" ?

2.
the package "pipewire-pulse" doesn´t exist in : guix packages list
That´s why I can´t install it.
Will this package be installed by : adding the sentence mentioned above 
(point 1.)?

At the moment my laptop with Guix SD in OBS recognizes the sound at 
least it moves the audiomixer sound level if I record something.
But after recording in playing the recorded stuff there is no sound at all.
The messages are: alsa didn´t find a device ...
At the moment everything bases on alsa.

3.
In the pipewire website it says, it is necessary to remove pulseaudio in 
order to get pipewire running. Also in the Arch Linux website.

This is a later question perhaps, first I have to get question 1. ready.

thanks for help
Gottfried
