[linux-audio-user] Problem with Jack

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

 



Hello,
It's more than a week that I'm trying to get off my problem without
success, so I ask you for help!
I would like to use Jack with alsa on my Ubuntu Hoary 5.04 for AMD64.
I downloaded all the alsa and jack packages needed but now I'm stuck,
I can't manage to use xmms or ardour with jack.

When i launch "jackd -v -R -d alsa -d hw:0 -r 44100 -H -z s" the output is:
getting driver descriptor from /usr/lib/libjack0.80.0-0/jack_alsa.so
getting driver descriptor from /usr/lib/libjack0.80.0-0/jack_dummy.so
getting driver descriptor from /usr/lib/libjack0.80.0-0/jack_oss.so
jackd 0.99.0

and this message goes on until i stop jackd. Then I receive this:

with qjackctl is exactly the same.

If I try to use XMMS I receive the error as my soundcard is not
configured and if i run ardour i hear the sounds but very fragmented
as if my pc couldn't play the files. With alsa everything goes well, i
can use xmms and other sounds... Could you help me? Thanks a lot.
