Hello Dan!
There are a few things you could try. You can just try to jack_connect your
soundcard ports:
jack_connect system:capture_1 system:playback_1
and the same for _2. That should give you some sound.
Did you start an alsamixer on your box? I know you get sound from ALSA, but
I have seen a USB device which wasn't agreeable with JACK, since it couldn't
find a few things or they were sketchy at best. On that thing alsamixer didn't
work.
Not exactly a jackmeter, but you can install ecasound and ecatools, if that
is a seperate package. Then you should do something like:
On one console you do:
ecasound --daemon -c
On another tty you type:
ecasignalview jack_auto,system jack_auto,system
Then if you generate some input you should see some lines of stars moving
and probably some numbers to indicate peaks.
When you're done quite ecasignalview by pressing q and then ecasound by q
<ENTER>.
So much for simple analysis. If you need something more specific, please say
so and I can try to think of other good CLI tools. :-)
Kind regards
Julien
