I have some trouble with jack, that I'm hoping
someone here could help
me with. First a bit about my system: It's a laptop running ubuntu 8.04
on a 2.6.24-23-rt kernel. I use an edirol ua-1a usb soundcard, since the
buildin HDA soundcard seems to be total crap.
Andre, if you're on Hardy, a simple troubleshooting step would be to
install updated jackd / qjackctl packages; I have Hardy backports for
all kinds of audio packages in my PPA:
