Original GitHub issue: https://github.com/devgianlu/go-librespot/issues/269

I need some help to troubleshoot this issue.
I'm trying to setup go-librespot via docker.
I'm using the proposed docker-compose file :

services:
  daemon:
    image: ghcr.io/devgianlu/go-librespot
    build: .
    network_mode: host
    userns_mode: keep-id
    volumes:
      - ~/.config/go-librespot:/config
      - ~/.config/pulse/cookie:/pulse_cookie:ro
      - /run/user/1000/pulse/native:/pulse_native # Replace 1000 with your UID
    environment:
      PULSE_SERVER: "unix:/pulse_native"
      PULSE_COOKIE: "/pulse_cookie"

When I try to play a track, I get the error below :

The docker compose you are using is for PulseAudio, not ALSA.

For ALSA you should be adding /dev/snd:/dev/snd as a volume.

But I'm using pulseaudio.
If I get it correctly, the problem is that the docker container does not see it and fallbacks on alsa (the issue title may be misleading, sorry about that).

What's your config file like? You have to specify the correct audio_backend.

ok, I've set the audio backend in the config to pulseaudio.

cat ~/.config/go-librespot/config.yml 
audio_backend: pulseaudio

Now I get a different error :

ive got a fully working Alpine based container running Pipewire (emulates pulseaudio) Snapcast and golibrespot that I wrote for another project, I am working on, i can tidy it up and share here if you want?

That issue has been fixed, I've published version 0.6.0, that should work.
