Public bug reported:
When I connect headphones, there is no sound in them. And the sound from
the builtin lodspeakers are disabled.
The "Playback devices" shows two devices: "HDMI audio" and "Built-in
Audio". The volume control on HDM audio has no effect, and the volume
control of the "built-in audio is automatically muted when headphones
are connected. It is not possible to un-mute it.
