When qjackctl opens, jack is usually started (AFAIK). Pulseaudio, for
better integration with JACK, gives up control of the soundcard to JACK
whenever JACK starts. This is not an error, its by design. The idea is,
if you're using JACK, you want it to have the soundcard, not pulse.
AFAIK, however, pulse only gives up a soundcard if jack takes it. This
should not happen if qjackctl doesn't start jack (I believe it does
start jack though).
