Greetings everyone,
Thank you for your consideration in my problems getting going with Pd. I am currently running Pd version 0.40-2 for Mac OS X 10.4 (PPC & Intel). On this computer, I have Mac OS X 10.4.8 running on a 1.67 GHz PowerPC G4 with 1 GB of RAM. I am using my built-in audio drivers.
When I try to run the audio test or any other audio-based patch, I get terrible glitches. Usually, they are spaced evenly in a 1-2-3-4 1-2-3-4 rhythm (only occasionally breaking that rhythm before settling back). No matter what I set the delay to, I get these glitches in the sound. No other audio program (like Ableton Live) is having any issues with the on-board sound card I am not running any other programs at the time of Pd. I can reproduce this issue faithfully through several releases back, even with special "extended" compiles.
Does anyone have any suggestions for how I can continue troubleshooting or correct this problem? Thank you kindly!
Best wishes,
Joseph Wilk

You could try setting the output sampling rate to 48000 as suggested
in this bug report where similar problems are experienced:

This did the trick! Thank you all. I wasn't aware of the Sourceforge page for PD. I'll search that in addition to the archives of this list and the info on the puredata.info site from now on. Thanks again, and have a great day!
Kind regards,
Joseph

hello joseph
i am not a mac user myself, but a student mate of mine had a similar problem with any version of pd (we tried about 4 different versions). However, we couldn't find any setting to avoid these glitches (these glitches have been also very regular, like: 'zlic ----- zlic-----zlic', like in your case). even setting the samplerate to 48000Hz didn't help, though that was mentioned in some mails before. also on her computer other applications ran fine, only pd was causing trouble. then we tried to run pd over jack and all troubles are gone. there is even a precompiled osx-binary of jack and an appropriate gui available, which makes the installing very easy: http://www.jackosx.com/
i hope that this will be a help also for you....

I am using PD on OSX, and I use JackOSX for anything that requires reliability. So try that, or try setting the delay in the "Audio Settings" dialog to a larger number. This increases the latency, and should lessen the chance of dropouts. I think the problem is that PD doesn't use the native OSX Core Audio drivers, but rather a set of Portaudio drivers. I've had less than ideal luck using Portaudio on OSX for anything, so my inclination is to see the problem there.
best, d.
