I would bet you are using the same device with pulseaudio. Pulseaudio
is supposed to let go of the card when you start jack, but this is
not working properly. Fixed in pulseaudio-3.0 (Ubuntu 13.04).
There are a few ways to get around this.
Installed is 1:2.1-0ubuntu4. Just checked for updates, and no updates
for pulseaudio, yet, in Linux Mint.
First of all, in a clean session, make sure pulseaudio is not using
your device when you start jack. I mean nothing. no open bwowser
tabs
with flash video, etc. This usually works.
That was the case: I listened to some youtube videos using firefox
prior to starting jacks. After reboot, jackd worked, naturally.
Once jack is started, you can have pulseaudio connect to jack (if you
have pulseaudio-module-jack installed, and you started jackdbus), by
setting jack as the output in the pulseaudio mixer.
If this means that it is possible to use 'regular' audio via jack, then
it seems useful. I presume then the devices (firefox, mplayer, etc...)
will not be seen in qjackctl's connections eg. it won't be possible to
use their input separately to route them.
If you don't want pulseaudio connect to jack, you should probably
either..
Set pulseaudio to use another device than what you want jack to use
That was it. I used pavucontrol to set the in/out device to the 1010LT
a few weeks ago. But then, if I set it back to the mobo's audio, I'd
have to get hardware to listen from the mobo audio outputs, instead of
using the Maudio monitors via the 1010LT. So it seems that your
suggestion of having the pulse audio jack module and jackdbus seems the
most practical.
