+OpenAL setup for general use (Linux)
+-------------------------------------
+As of the July 2004 release of OpenAL it is best to add at least the
+following line to your ~/.openalrc file on Linux because it wil find out
+what audio backend to use, starting with the most appropriate:
+
+(define devices '(native alsa sdl esd arts null))
+
+
+
+ALSA surround sound (5.1) setup
+-------------------------------------
+(taken from http://floam.ascorbic.com/how-to/alsa5.1)
+
+Make a ~/.openalrc, we are telling OpenAL that we want surround sound and
+we want to use ALSA instead of OSS.
+
+(define speaker-num 4)
+(define devices '(alsa))
+(define alsa-out-device "surround40:0,0")
+
+
+
+IRIX surround sound (5.1) setup
+-------------------------------------
+To add 4 channel surround sound on IRIX hardware that supports in
+directly you can just add the following line to your ~/.openalrc file:
+
+(define speaker-num 4)
+
+To add 4 channel surround sound to IRIX systems that have more than one 
+stereo output you can add the following section to your ~/.openalrc file
+(for a typical O2 configuration):
+
+(define speaker-num 4)
+(define native-out-device "Analog Out")
+(define native-rear-out-device "Analog Out 2")
+
+or alternatively:
+
+(define speaker-num 4)
+(define native-out-device "A3.Speaker")
+(define native-rear-out-device "A3.LineOut2")
+
+
+
+(Note the following section is obsolete as of the July 2004 release of 
+OpenAL, since your could command OpenAL to use ALSA or Arts directly)
+
