ok, then you need something similar like below:
pcm.dup4ch {
type hooks
slave.pcm {
type hw
card 0
device 0
}
hooks.0 {
type ctl_elems
hook_args [
{
name "Rear Path"
preserve true
value true
}
{
name "PCM Reverb Playback Volume"
index { @func private_pcm_subdevice }
preserve true
value 127
}
]
}
}
then run "aplay -Ddup4ch some-2ch.wav"
