I normally don't run on ALSA, so I don't have much experience with this
feature. Even harder, Nedko, who implemented the DBUS card serveration
for jackd2 don't run pulseaudio.

I tried it on my laptop yesterday. qjackctl wasn't able to start jackd
one or two times, but then, out of a sudden, it worked. Terminating
jackd also worked, mplayer was playing all the time to pulseaudio.

Looks like a race condition or some kind of first-time hiccup. Now I
can't even reproduce the behaviour, jackd can always acquire the card.
Weird.
