I have the same problem, using jackd and qjackctl on Kubuntu 9.04, and
repeatable when starting qjackctl from the command line (recipe below).
jackd and qjackctl (and a bunch of other stuff) were installed for me as
dependencies when I installed rosegarden.
sudo apt-cache show jackd reports:
Version: 0.116.1-3ubuntu3
sudo apt-cache show qjackctl reports:
Version: 0.3.4-0ubuntu2
uname -a reports:
Linux orac 2.6.28-9-generic #29-Ubuntu SMP Sun Mar 8 02:03:17 UTC 2009
i686 GNU/Linux
Recipe to reproduce the bug:
qjackctl
/usr/bin/qjackctl: 28: list: not found [ seems to be complaining about the
line: JACK=$($PACTL list | grep jack-sink) ]
Using JACK for audio
[gui entitled JACK Audio Connection Kit [(default)] Stopped. appears.
