Well, even this doesn't seem to want to work for me at the moment :-( I'm
still only getting audio from the front speakers.
[ adamk@sorrow ~ ]$ cat .asoundrc
pcm.ch4dup {
type plug
slave.pcm surround40
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
[ adamk@sorrow ~ ]$ aplay -D ch4dup saved/sounds/Thunder.wav
Playing WAVE 'saved/sounds/Thunder.wav' : Signed 16 bit Little Endian, Rate 22050 Hz,
Stereo
Any further ideas?
Adam
