I thinj he is using realtime kernel, as he is running jack with the -R flag (reatime) otherwise jack wouldn even start.<br><br><div class="gmail_quote">2010/3/4 Pierre Massat <span dir="ltr">&lt;<a href="mailto:pimassat@gmail.com">pimassat@gmail.com</a>&gt;</span><br>

I&#39;m encountering bad audio behvaiour with pd+jack. Pd is reporting DIO errors even without any patch open. When I open one of the simple example patches I get very frequent breaks in the audio sometime these are even at a regular rate (around 120 bpm).<br>


<br>
I&#39;m using FC10 with jack and a firewire soundcard.<br>
I&#39;m starting jack with:<br>
/usr/bin/jackd -R -t10000 -dfirewire -r48000 -p256 -n3 -i2 -o6<br>
(also tried p128 &amp; 512).<br>
<br>
I can play soundfiles with no problems using snd so it seems the problem might involve some interaction between pd &amp; jack. I don&#39;t get this audio problem when I&#39;m using pd with a USB soundcard (without jack) on the same machine.<br>


Any ideas how to track the problem and (hopefully) fix it?<br>
<br>
