But let's say I just want to start pd like this:
pdextended -jack channels 2
Within PD, when I click on 'test audio and midi', I get the following DIO errors in pd along with no test tone (after I select "60", of course) :
error: 2: can't open
audio I/O error history:
seconds ago error type

Pasuspender is a way to make PulseAudio let go of the soundcard when JACK wants to access it. This *is* nessisary on systems where Pulse is the main sound daemon, but as KX uses JACK for all its audio needs, it will not have any effect.
"Error: 2: can't open" did catch my eye though, are you passing any special arguments to your "dac~" in the patch? like "dac~ 1 2" or something to open the first & second channel? I've had problems there before, either because it did (or did *not*) start from 0. Can't remember the details, but perhaps that's it?
