I have an existing application, which uses OSS interfaces, which will do
what I want if I can just configure ALSA to create a different emulated
OSS sound device for each input channel on the sound card. (Or, perhaps
for stereo pairs of input channels). So, is there a way to configure
ALSA to do this, and if so, what is it?
It should work if you use the aoss script from the alsa-oss package
which maps /dev/dspX to an ALSA PCM device named dspX, and define
these devices as capture devices for the desired channels with the
dsnoop plugin.
