[linux-audio-user] yamaha rp-u200 usb-audio and jack

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 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details registered builtin port type 32 bit float mono audio capabilities: =i cap_setpcap,cap_ipc_lock,cap_sys_nice,cap_sys_resource+ep loading driver .. new client: alsa_pcm, id = 1 type 1 @ 0x8057d18 fd = -1 apparent rate = 44100 creating alsa driver ... hw:0,1|hw:0,1|1024|2|44100|0|0|nomon|swmeter|rt|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0,1 for 32bit samples trying 24bit instead Couldn't open hw:0,1 for 32bit samples trying 24bit instead Couldn't open hw:0,1 for 24bit samples trying 16bit instead Sorry. The audio interface "hw:0,1" doesn't support any of the hardware sample formats that JACK's alsa-driver can use.
