I've read this a couple of times over the years but it still
does not make much sense (to me)...
http://alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html
As a baseline, say I started with this, where could I go
from here to get an app (ie; Amarok) to play back out two
soundcards at once ?
# cat .asoundrc
pcm.NVidia { type hw; card NVidia; }
ctl.NVidia { type hw; card NVidia; }
pcm.USX2Y { type hw; card USX2Y; }
ctl.USX2Y { type hw; card USX2Y; }
pcm.shared {
type dshare
ipc_key 321456 # any unique value
ipc_key_add_uid true
slave NVidia
slave USX2Y
bindings {
0 0
1 1
}
}
