Some guesses;<br><br>Considering that PD is rather like us in that it&#39;s cross-platform and for realtime stuff I&#39;d predict that PD also uses RTAudio so it might not be so surprising that it behaves the same way. It might be a logical next step to try something realtime that uses a different library.<br>
<br>Another possibility: if any one random program is taking a lot of CPU then there will be audio hickups but that needn&#39;t mean the audio system itself has a problem. Did you check how CPU usage is distributed?<br><br>
The world&#39;s history is full of incidences of blaming something (or preferably somebody) else first before doing a lot of work yourself so let&#39;s try if we can do this as well :¬).<br><br>Kas.<br>
