this won't work. the hw:N device requires the input format to match the
h/w caps (channel count, SR, bit depth, interleaved, etc. etc.)

my understanding was that ALSA's default handling of routing an N
channel signal to M channels where N>M is that the N get mapped to all M
in a repeating fashion. maybe this has been changed, and you just get
the first N channels, with the rest silent.

martin, there is no way to use just ALSA device addressing to specify
specific channels. you would have to set up an ALSA pseudo-device with a
"route" specification to do this. its probably not what you want.

as was mentioned, just using JACK will be much easier.
