Configuration

Sound

Important
The user must belong to the audio and pipewire groups, otherwise the daemon will not connect to the sink.

Install media-video/pipewire with the following USE flags: sound-server, pipewire-alsa, bluetooth (optional).

The sound doesn't work out of the box, so you have to manually specify the sink and source. In the case of Bluetooth or 3.5mm jack, no additional configuration is required.

FILE /etc/pipewire/pipewire.conf.d/alsa.conf

context.objects = [
  { factory = adapter
    args = {
      factory.name	= api.alsa.pcm.sink
      node.name		= "alsa-sink"
      node.description	= "PCM Sink"
      media.class	= "Audio/Sink"
      api.alsa.path	= "hw:0,5"
    }
  }

  { factory = adapter
    args = {
      factory.name	= api.alsa.pcm.source
      node.name		= "alsa-source"
      node.description	= "PCM Source"
      media.class	= "Audio/Source"
      api.alsa.path	= "plughw:0,1"
    }
  }
]
