Hi Guix,

who of you have experience in audio-interfaces for Guix?

Which Audio-interfaces are supported in Guix?

If I get one,
would it be difficult to install it?

thanks for help

Gottfried

Hi! I'm using Native Instruments Komplete Audio 2 on my GNU Guix System, it didn't need any additional configuration, I just plugged it in. I'm using pipewire if it makes any difference.

Similarly plug-and-play here with Pulse and an

00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

(although I haven't been able to suss out how to make the audio 
available over a ssh tunnel, and I vaguely remember that being easier in 
Ubuntu).

I bought a Komplete Audio 1 interface,
but now:

they offer only a window or Mac support software.

How did you manage to use it in Guix?
Which package do you use?
obs, audacity, ardour ...?

I installed pipewire, but
when opening obs, it didn't give this option of pipewire.
There is alsa and pulseaudio.
How can I change this?

Did you put something in your config.scm?

thanks for help

Lesik will give you a better answer, although "the Komplete Audio 1 is
class-compliant." [1]

You can investigate a lot already with 'lsusb' and then with 'alsamixer"
(from alsa-utils).  Alsamixer is a console program that uses Ncurses for
graphics and has some odd keybindings [2] but you may just have to
unmute it.

My understaning is all modern sound daemons such as PulseAudio or
Pipewire are built on top of ALSA, which stands for Advanced Linux Sound
Architecture.

Please send the songs you will records with your new system!

Kind regards
Felix

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

If I connect my Komplete Audio 1 with usb to my laptop:
I get this message:

That is without installing pipewire.
I installed pipewire etc, but after an sudo guix system reconfigure...
I had no sound at all. I lost what I had, and I didn't get pipewire.
So I had to change to an older generation to get rid of everything I had 
installed.

Approx. 2 years ago Csepp said: Guix home can´t be deleted if installed.
So I didn´t dare to install it.
Secondly I am not on that level to configure my system.

So I can´t use my audio interface at the moment.

Thanks for help

Gottfried

Re: audio interface for Guix

The fact that your interface is not listed in lsusb is quite strange. For the experiment, I even tried booting from the Guix installation image, and my interface was listed in lsusb. Are you sure your interface is working? Could you try it with another USB port, PC, or distribution?
