Well with the stock install of Ubuntu studio 10.10 except for the graphics accelerator upgrade the audio was still glitching the same as with 9.10 puredyne. So I done all the upgrades possible and that seemed to get the patch running without gem with a 50ms buffer. There is no glitching while messing with the guis in pure data like there is in 9.10 so I'm guessing it's either a window drawing routine or something to do with alsa or the audio codecs that got upgraded. Now maybe I can figure out how to tinker with the alsa drivers to lower the latency.
