I have mplayer set up to connect to JACK. Now I have zita-mu1, with the
idea of having a single volume control for the output. But everytime
mplayer starts, it connects to JACK, bypassing zita-mu1.
Ideas?

Did you specify zita-mu1 to connect to when you started mplayer?
I don't have zita-mu1 installed but I believe it should be something like this:
mplayer -ao jack:port=zita-mu1
check with jack_lsp -c which port you have.

This is what I use. It works only because *usually* jack will report the first
two ports of zita-mu1 to be 'in_1.L' and 'in_1.R'. Actually jack has no

of port order, so you can't count of this.
If necessary I have another solution which will always work, but it requires
the use of jack_proxy. This is one of the three small apps in the jack_utils
package you can find on my website. Let me know if you need any help with this.

You can also start mplayer with
mplayer -ao jack:port=noconnect
then it will create JACK output ports but not connect them to anything.
You can then use an auto-connect tool to establish the connection to
zita-mu1 and also from zita-mu1 to your playback ports as soon as their
ports appear.
For example, with jack-matchmaker
<https://github.com/SpotlightKid/jack-matchmaker<, this would would work:
jack-matchmaker -e \
"/MPlayer.*:out_0$/" zita-mu1:in_1.L \
"/MPlayer.*:out_1$/" zita-mu1:in_1.R \
zita-mu1:sel_out.L system:playback_1 \
zita-mu1:sel_out.R system:playback_2
Start this *before* you start mplayer. You can also put these port
patterns into a file and use the -p option for jack-matchmaker.
I don't have zita-mu1 installed but I believe

mplayer -ao jack:port=zita-mu1
This is what I use. It works only because *usually* jack will report the first
two ports of zita-mu1 to be 'in_1.L' and 'in_1.R'. Actually jack has no notion of port order, so you
can't count of this.
A side note: you can set meta data on JACK ports to define the port
order, but since mplayer respect this meta-data, it's not helpful here.

The last two lines should probably refer to zita-mu1:mon_out1.L and R.
The sel_out ports are before the volume controls, they are meant for e.g.
a spectrum analyser.

Thank you all for the many different ways to do things!
I added this to my mplayer config file
ao=jack:port=zita-mu1,jack,alsa
Mplayer connected to zita's in_1.l and .r without asking questions.
