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.<br /><br />&quot;Error: 2: can&#39;t open&quot; did catch my eye though, are you passing any special arguments to your &quot;dac~&quot; in the patch? like &quot;dac~ 1 2&quot; or something to open the first & second channel? I&#39;ve had problems there before, either because it did (or did *not*) start from 0. Can&#39;t remember the details, but perhaps that&#39;s it?<br /><br />-Harry
