[Pkg-utopia-maintainers] Bug#999686: added suggested fix

[Gert van de Kraats]

In fact this bug is a problem at wireplumber, not at pipewire-pulse.

Program wireplumber uses config-file

/usr/share/alsa-card-profile/mixer/paths/analog-output-speaker.conf .

Like at pulseaudio the problem can be solved by commenting out thye next 
lines:

; Make sure the internal speakers are not auto-muted once the system has
speakers
[Element Auto-Mute Mode]
enumeration = select

[Option Auto-Mute Mode:Disabled]
name = analog-output-speaker
