Problem with ALSA's JACK plugin

Hi everybody,

I'm trying to set up ALSA to route all audio output to jackd using ALSA's JACK 
plugin (compiled it from source from 
ftp.alsa-project.org/pub/plugins/alsa-plugins-1.0.15.tar.bz2 as it doesn't 
seem to be in the repository).

I set up /etc/asound.conf as described here:
http://alsa.opensrc.org/index.php/Jack_(plugin)

Unfortunately it doesn't work this way, I won't get any sound out of ALSA any 
more. Trying to play some audio with mplayer for example just gives me:

JACK tmpdir identified as [/dev/shm]
Enhanced3DNow! detected
SSE2 detected
alsa-init: format s16le are not supported by hardware, trying default
alsa-init: unable to set format: Invalid argument
Could not open/initialize audio device -> no sound.
Audio: no sound

Native JACK applications like Ardour work flawlessly, though.

If anyone has an idea what to do about this, I'd appreciate any help. :-)

Best regards,
Victor
