Hi -
I recently found out about JACK through SilentJack no less and realize I may
have found a good tool to do silence detection for my audio streams.
I've got Jack setup and running along with JackMeter and SilentJack. This is
running on an OpenSuse box (11.3) running Gnome and qJackCTL.
I am running VLC to open my audio streams (mix of Real, Windows, MP3,
Quicktime).
Does anyone have any tutorials for automating Jack though? It seems
cumbersome to have to recreate the various audio connections (say after
rebooting). I don't see a way to statically assign output ports using VLC.
Ideally, I'd like to automate as much as possible upon logging into the
machine.
Last question - Does anyone have any examples of scripts to run after
SilentJack has detected silence? Obviously, I was thinking about an email
alert. I wasn't sure about the syntax needed though.
Thanks for any help or pointers.
Tim

If you have a rather static setup, and already use qjackctl, then you
can use its patchbay. It may be a bit painful to set up, but I guess
it's fairly automatic from there on.

So patchbay is similar to the audio connections panel, but I can save the
"connections"? I'll have to look into that...
Does anyone have experience/examples of SilentJack alerts/commands then? I've got it
outputting to the console, just not sure how to get it to do x when silence happens.
Thanks.

Tim,
VLC's audio connections are pretty easy to "automate".
Open VLC -> Tools -> Preferences.
Bottom left there should be an option "Show advanced?", click "all".
Go to Audio (top left), expand it, go to "Output modules", click JACK, tick
"enable auto connect".
That's from memory, so it might not be 100% correct.. but that's the general
gist of it. :-)
Ill leave the rest to other peoples, -Harry

The problem I've always had with VLC is that it disconnects and
reconnects after every track -- and that to system out 1 & 2
respectively. So if you are trying to route VLC somewhere else across
multiple tracks, you need a way to automate a reconnect.
If anyone has a workaround for this behavior, I'm all ears.

Last I checked VLCs autoconnect was regex based, it's just hidden
somewhere in the config.
