Hi list,
I'm know this has been asked a thousand times already but could someone
please point me in the direction of instructions to enable non-jack
applications (like vlc) to work concurrently with jack? The well-known
situation is that jack "hogs" audio and makes other applications
unusable. How to get around this?
Many thanks,
Peter

There are three options:
1: use pulse audio with jack-sink - easy
2: use the jack-alsa plugin for alsa - not so easy
3: get a second audio device just for normal playback - $$$ (also pretty
easy)

Thanks.
I've installed pulseaudio-module-jack but "Pulseaudio JACK Sink" is not
showing up in the connections in qjackctl or in volume control. What am
I missing?
In case it's relevant I'm running Ubuntu 12.04 and qjackctl 0.3.8.

Please disregard this last email. It's working as it should now.
Thanks again.

One of two things have to happen. Either jack has to be run as jackdbus or
the jack sink module has to be loaded manually after jackd is running.

Today I used these instructions successfully
to route ALSA and Pulseaudio outputs through JACK.
http://trac.jackaudio.org/wiki/WalkThrough/User/PulseOnJack
For Skype to work via Pulseaudio on my amd64 Debian system I
needed to install an additional library: libpulse0:i386
Greetings,
Joel
Many thanks,

The situation is ALSA only allows for one connection at a time, so anything
connected directly locks everything else out. So you need some other layer to
share your device. Either pulse or jack will share your ALSA device for you, but
only one of them can be connected to ALSA at a time. Pulse does not support the
connection jack needs since jack provides types of access to the device that
pulse does not. So jack cannot connect via pulse, hence you have to connect
pulse via jack instead.
This was difficult some time ago, but now the solutions offered earlier in the
thread exist. Pulse and jack cater for very different needs.

As you mention vlc, note that many multimedia players feature a jack
audio output plugin. In the case of vlc (and in debian-based distros at
least) this doesn't work by default but you have to install a separate
package, "vlc-plugin-jack" (and then enable jack in the audio preferences).
