My assumption is: The first mixer device it finds (usually /dev/mixer0)
will be used. But how to change this?
a) Check if there is a command line switch (like -f to the mixer
program) to select the mixer which should be manipulated. But
how to check? With "man <something>", the question arises how
the mixer control is actually called. From a bit of googling
I found "mate-mixer" and "mate-volume-control-applet" as
possible names. There probably won't be a manpage for them,
because documentation is often considered "not needed" over
there in GUI Linux land... :-(
Maybe this is a possible starting point:
https://www.linuxquestions.org/questions/slackware-14/mate-1-10-sound-mixer-4175545660/
b) Use FreeBSD's sysctl facility to change the mixer order. With
the device.hints file, this could be possible (so /dev/mixer1
assigned to the front connectors becomes /dev/mixer0 which is
then controlled by the Mate volume control slider).
It's all nice and fine if the defaults work for you. But if you
have a slightly different requirement, it seems you're doomed.
A little sidenote for the script: For "for i in 0 1 2 3 4", you
could use "for i in `seq 0 4`". :-)

Hve you considered using a different mixer program? I've just
tried ye olden xmixer: it has both "man xmixer" and a way to
select the mixer via "xmixer -m <device>".
There's still something that I just thought of: What if inside
Mate, ALSA is being used? L stands for Linux. Could that be a
reason why there is the narrowminded assumption that "only one
mixer in the system" seems the way the mixer works?

Exactly! :-)
