hi list

i try to get the quattro talking with jack, therefore i compiled the
kerenel 2.6.7 (debian) again
with the realtime lsm-0.1.1 module, which i'm able to load "modprobe
realtime any=1 allcaps=1"

dmesg says:
selinux_register_security: Registering secondary module realtime
Realtime LSM enabling all capabilities
Realtime LSM initialized (all groups, mlock=1)

i configured jack 0.98 from source, as mentioned in the readme with
/mnt/ramfs enabled.

when i start jackd with:
jackd -R -P0 -d alsa -d quattro1 -r 48000
it's not working with the following output:
jackd 0.98.1

loading driver ..

creating alsa driver ...
quattro1|quattro1|1024|2|48000|0|0|nomon|swmeter|-|32bit
configuring for 48000Hz, period = 1024 frames, buffer = 2 periods
Couldn't open quattro1 for 32bit samples trying 24bit instead
Couldn't open quattro1 for 24bit samples trying 16bit instead
Sorry. The audio interface "quattro1" doesn't support any of the
hardware sample formats that JACK's alsa-driver can use.
ALSA: cannot configure capture channel
cannot load driver module alsa

i have the latest alsa-cvs installed and xmms with alsa and alsaplay
sounds ok. pd is also working but
it seems to click with alsa, in oss mode it works with occasional
clicks. i have the .asoundsrc taken from
the alsa-project page, is it still uptodate? i put it in /root and
/home/userx.

any idea what to do?

marc
