Hi,
Ihave a yamaha rp-u200 usb "soundcard".
Nice,at the same time it is my hifi and surround-ampli
and my radio.
The capture-channel doesn'tb seem to work (normal?)
With alsa,one of the two playback-channels is working.
Not so bad....
But jack doesn't want to start with this device.
Is it that "real24bit"-problem for usb-cards?
Shouldn't it work?
Anyone knows about this?
When I start jack for this device I get the following output:
jackstart -Rv -d alsa -d hw:0,1 -r 44100
back from read, ret = 1 errno == Success
getting driver descriptor from /usr/lib/jack/jack_dummy.so
getting driver descriptor from /usr/lib/jack/jack_alsa.so
jackd 0.94.0

Sorry. The audio interface "hw:0,1" doesn't support any of the hardware sample formats that JACK's alsa-driver can use.
ALSA: cannot configure playback channel
cannot load driver module alsa
Thanks for help or comment.
