This provides a daemon that implements the same D-Bus API as callaudiod
in aports community/callaudiod, but works with the new audio profiles
generated by PulseAudio v17 and PipeWire v1.2 for pine64-pinephone
that the aports package's daemon does not.
This daemon is specific to the pine64-pinephone since it has
a hard-coded list of profiles and ALSA devices. If other devices also happen
to have UCM settings that trigger PulseAudio / PipeWire to generate
the combinatorial audio profiles that callaudiod cannot handle, and if
a callaudiod fix / alternative does not appear, then the maintainer (me) is
open to making this daemon more broadly useful for other devices, say by
having the hard-coded strings in device-specific config files.
