Arcam AV Amplifier ALSA Control plugin

======================================

This plugin exposes the controls for an Arcam AV amplifier

(see: http://www.arcam.co.uk/) as an ALSA mixer device.

To use this plugin you will need to connect the amplifier

to the PC using an RS-232 null-modem cable and use the

following ALSA configuration:

	ctl.arcam_av {

		type arcam_av

		port /dev/ttyS0

	}

The "port" parameter is required and indicates the serial

port to be used to communicate with the amplifier. There is

an optional "zone" parameter, which accepts a value of

either "1" (default) or "2", that indicates which of the

amplifiers zones should be controlled.

NB: You must ensure that any user accounts that are to use

this plugin have both read and write access rights for the

configured serial port.

This plugin was developed and tested using an Arcam AVR 300

amplifier. I believe most Arcam amplifiers use a sufficiently

similar control system to be compatible with this plugin but

your mileage may vary.
