Your right that it is not easy.
I was under the impression that something like:
----
pcm.first {
type hw
card 0
device 0
}
ctl.first {
type hw
card 0
}
pcm.second {
type hw
card 1
device 0
}
ctl.second {
type hw
card 1
}
pcm_slave.sl {
pcm second
rate 44100
}
pcm.c1 {
type copy
slave sl
}
ctl.c1 {
type hw
card 0
}
----
Would allow you to do what you want. The plugins docs says it will copy
from master pcm to the slave pcm. I assume that the master is the first
device hw:0,0.
Did you try anything like the above?
I would but I'm testing alsaplayer and it is having problems with
releasing the ALSA pcm device currently so I have to shut down first.
HTH.
