Forgot to add, never had much luck with dark ice + icecast. Liquidsoap
+ icecast is rock solid and can do all sorts of fancy stuff including
silence detect and compression so might be the tool you're looking for.

JACK is quite simple.
You need to kill off pulse audio first.
sudo nano /etc/pulse/client.conf
find the line: ;autospawn = yes
change it to: autospawn = no (note the removal of ;)
Now kill pulse: pulseaudio -k
Next up, install qjackctl (sudo apt-get install qjackctl). Also known
as the JACK Connection Kit.
Load that up, click on setup and pay attention to the sample rate and
the interface settings. You might have to change it to hw:0 or hw:1
especially if you're using a USB card or have an inbuilt sound card
and a pro one.
Once you're happy with that. Press OK, then click Start.
If you've got the settings right JACK will say Started and everything
is happy. If not try a different hw:0 etc. (you can find these out
with aplay -l).
From there start playing some sound. VLC will use jack if you install
it with the jack plugins (I think its vlc-jack-plugin or
vlc-plugin-jack). Just go into VLCs preferences and select JACK output.
When you hit play VLC will auto create ports and connect as necessary.
(Audacity also does something similar if you prefer to test on that).
If JACK is starting but you're still not getting any sound, check
alsamixer to make sure your in/outputs aren't muted.
Obviously make sure you've got something that makes sound connected to
system:playback_1 & 2 (usually your main speaker out).

Is there a guide anywhere to getting JACK up and running? I've tried
to get it working on two different machines, and find that I can't
get sound from the sound card input to go anywhere, nor sound from
any piece of software to show up at the output of the sound card.
In my latest attempt to record something into Ardour, I managed to
lock up my computer, and now it locks up every time Ardour starts.
Eventually, I'd like to find a program that can do audio compression
to run with Darkice and icecast on a streaming encoder instead of
installing something like a Compellor in front of it.
