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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
