Hello,
I'm trying to play 2-channel audio files on all the 6 channels my
nforce-sound provides, with this asound.conf (found
onhttp://alsa.opensrc.org/index.php?page=FAQ028):
------------------
pcm.ch51dup {
type route
slave.pcm surround51
slave.channels 6
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 0.5
ttable.1.4 0.5
ttable.0.5 0.5
ttable.1.5 0.5
}
------------------
Aplay gives this error:
------------------
[EMAIL PROTECTED] earendil $ aplay -Dplug:ch51dup /tmp/test.wav
Playing WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo
aplay: set_params:882: Can't use period equal to buffer size (5017 ==
5017)
------------------
Any ideas??
