Hi,
I own a soundblaster 4.1 and I experience the following problem: I can't get
the rear channel to work. There isn't even a volume control for it (neither
in amixer nor in alsamixer). I'm using the snd-ens1371 driver that should do
the job.
The card is a basic design using a CT5880 PCI controller and a Sigmatel
STAC9708T codec. That's what's printed on the chips.
Both
aplay -D "hw:0,0" /tmp/test.wav
aplay -D "hw:0,1" /tmp/test.wav
play through the main channel.
Any thoughts?
