Hi,
you could use the alsa rate plugin.
I used following .asoundrc for testing my driver:
pcm.au600playback {
type dmix
ipc_key 1024
ipc_perm 0777
slave {
pcm "hw:2,0"
period_time 0
period_size 96
buffer_size 1920
format S16_LE
periods 4
rate 9600
}
}
pcm.au600capture {
type rate
slave {
pcm "hw:2,1"
format S16_LE
rate 9600
}
}
pcm.duplex {
type asym
playback.pcm "au600playback"
capture.pcm "au600capture"
}
aplay -D plug:duplex <filename>
cheers,
Markus
