.asoundrc plugin setup

.asoundrc plugin setup

[Antonio Willy Malara]

i have some troubles with an usb-audio device (an imic) on linux ppc 
(an ibook2), i think becouse of endianness related troubles..

my big trouble is that jack says:

willy@Zeryn:~$ jackd -d alsa -d hw:1
jackd 0.80.0
[...]
JACK compiled with System V SHM support
loading driver ..
creating alsa driver ... hw:1|hw:1|1024|2|48000|nomon|swmeter|rt
open
Sorry. The audio interface "hw:1"doesn't support either of the two 
hardware sample formats that jack can use.
ALSA: cannot configure capture channel
starting engine
engine driver not set; cannot start
[...]

i've setupped an .asounrc like that:

pcm.imic {
         type hw
         card 1
}
  ctl.imic2 {
         type hw
         card 1
}
  pcm_slave.sl3 {
         pcm imic
         format S16_LE
}
  pcm.imic2 {
         type plug
         slave sl3
}

and jack at least start, but it dont playback anything:

willy@Zeryn:~$ jackd -d alsa -d imic2
jackd 0.80.0
[...]
creating alsa driver ... imic2|imic2|1024|2|48000|nomon|swmeter|rt
open
You appear to be using the ALSA software "plug" layer, probably

its a mine fault or alsa fault?? i think that with that .asoundrc this 
things should work...

tanks for attention
