Here is an example that works for an Delta M44 card for input and output
This card uses the snd_ice1712 module.
Content of .asoundrc
=========================
pcm.SDR1000_card {
type hw
card M44
}
ctl.SDR1000_card {
type hw
card M44
}
pcm.dmixer {
type dmix
ipc_key 4714
slave {
pcm SDR1000_card
format S32_LE
period_time 0
channels 2
period_size 512
buffer_size 4096
}
bindings {
0 0
1 1
}
}
pcm.dsnooper {
type dsnoop
ipc_key 4711
slave {
pcm SDR1000_card
format S32_LE
period_time 0
period_size 512
buffer_size 4096
}
bindings {
0 0
1 1
}
}
pcm.SDR1000Play {
type plug
slave {
pcm "dmixer"
}
}
pcm.SDR1000Record {
type plug
slave {
pcm "dsnooper"
}
}
=================================
M44 is the name of the card you see in /proc/asound
You can use SDR1000Play as sink and SDR1000Record as source.

Here's a discussion of a strongly-related issue with the M-Audio 2496
that seems to imply that the driver only offers 10 channels, not the
conventional '2', and so things that would ordinarily expect '2'

OK thanks for that. I guess I should be able to craft an asoundrc that
creates a virtual device with 2 channels that just points at the right
place and gnuradio will be happy.
