Extend the wireplumber recipe to enable the session manager on all
platforms and provide board specific audio initialization if needed.
A set-audio-defaults.sh script is packaged to configure default audio
sinks and sources at runtime, managed by a dedicated systemd service
that runs after wireplumber starts.
