PiAudio is a service that integrates with ALSA, the sound sub-system on the Raspberry Pi, and lets sound samples be played via Paula on the Amiga.
The piaudio program should run on the Amiga. It allocates two sounds channels, one left and one right. Using the following command the piaudio program can run in the background:
run piaudio >NIL:
The file .asoundrc should be stored in /home/pi on the RPi. Most programs that play audio on the RPi can then be used. One such program is mpg123, which is started as:
mpg123 -a amiga song.mp3
