Hello, I’m trying to setup mopidy on my raspberry Pi 3B+.
I first tried to make it boot with runeaudio: https://www.runeaudio.com/ as I was used to it and knew it worked well out of the box with the raspberry Pi 3B. But it didn’t boot so I thought it was a good occasion to give NixOS ARM a try.
So I tried to configure mopidy but quickly realise that I couldn’t produce any sound, neither with mopidy, nor with aplay.
Here is my configuration (using nixos 21.05 channel):
{ config, pkgs, lib, ... }:
let
unstable = import <nixos-unstable> {};
in
{
disabledModules = [ "services/audio/mopidy.nix" ];
imports = [
./mopidy.nix
];

boot = {
loader = {
grub.enable = false;
raspberryPi = {
enable = true;

uboot.enable = true;
};
timeout = 1;
};

};

hardware.pulseaudio = {

package = unstable.pulseaudioFull;
};
boot.loader.raspberryPi.firmwareConfig = ''

When launching pavucontrol, I see only “Dummy Output” in the Output Devices tab. Playing wav files with aplay, I see the sound playing in pavucontrol.
