Interesting.  I tested this, but this time with a YouTube video playing in
Firefox, with two methods.

In the first test, I started video in YouTube then select qjackctl from the
menu.  I have only started qjackctl, not jack, and video losses sound but
starts again when qjackctl is shut down.

Next, I start jackd via command line " jackd -dalsa -dhw:1 -r44100 -p512
-n3" and the jackd will not start because "the playback device "hw:1" is
already in use".

Keep in mind that I'm running Ubuntu Studio and the menu entry is calling
"pasuspender /usr/bin/qjackctl" so this isn't really a script.  The Ubuntu
Studio team will need to address this once we sort out getting how jack and
Pulse Audio and working together.


For the automatic stuff you want to make sure that Setup -> Misc -> "Enable
> D-Bus interface" is checked as well.


 I did that last night before the tests tonight and even verified that it
was still enabled.


...and start "jackdbus" instead of "jackd" here.


I tried and it said that "jackdbus should be auto-executed by D-Bus message
bus daemon.
If you want to run it manually anyway, specify "auto" as only parameter"

Trying "jackdbus auto" doesn't seem to do anything.  No comments back, just
"scott at natty-studio:~$" at the next line waiting for a command.


Hmm, under this scenario, could you supply the output of "sudo fuser -v
> /dev/snd/*"? It sounds like totem does not use pulseaudio but goes to the

scott at natty-studio:~$ sudo fuser -v /dev/snd/*

I never saw any Pulse Audio sinks in the qjackctl "Connect" window under any
of the tabs.

I did not see a place to set the output to a jack sink in "pavucontrol".
Under the "Playback" tab I can see Totem playing the music but I can only
choose to set it to either of my audio interfaces: Internal Audio Analog or
ICE1712 [Envy24] PCI

I should point out that I haven't loaded either of your modules yet.
However, I am running Ubuntu Studio Natty with jackd2 installed.

Lastly I want to point out that I appreciate your time and effort to helping
me understand this so I can provide better functionality for our users.

Cheers,
