you can use the pre-defined surround40 device, *but* jackd will
assume it also has 4 input channels and refuse to start, so you have
to define a new device based on surround40.
add this to your .asoundrc:
ctl.jack42 {
type hw
card 0
}
pcm.jack42 {
type asym
playback.pcm {
# route for mmap workaround
type route
slave.pcm surround40
ttable.0.0 1
ttable.1.1 1
ttable.2.2 1
ttable.3.3 1
}
capture.pcm {
# 2 channels only
type hw
card 0
}
}
then specify "jack42" as your alsa device when starting jackd. works
like a charm for me.

hi,
what is the best way to get 4 independent outputs from an sblive!
i am using pd with jack but in qjackctl i only see 2 alsa_pcm playback
devices. Is it possible to get 4 outputs using an sblive and jack?
if not what's the best approach... alsa? oss?
thanks,
