I have a mythbuntu setup with S/PDIF sound going to an external receiver that amplifies the sound into a 5.1 surround speaker arrangement. Currently I have to control the volume on the receiver (Arcam AVR 280) separately from controlling the rest inside the mythbuntu box. I have hooked up the Arcam receiver via its serial interface to my mythbuntu box (on a USB->RS232 connection) and can, in principle, control the Arcam amplifier volume through a sequence of published control codes (the manual has a very detailed appendix explaining how).

Is there a way that I could use to hook volume change request coming from the mythtv setup to a script that control the amplifier volume?

Apparently, others are wondering the same and not getting anywhere.
