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.

From Vista I was just able to set the latency to 12ms in pd 042.5 vanilla without loading any extra libraries besides the moog~filter from ggee and this did not have any audio dropouts. This is without GEM
I will try this same thing with the same patch in Uuntu Studio 10.10.
Earlier I noticed from puredyne that whenever the audio glitches the cpu% jumps to 1% instead of 0 for soundcard IRQ process. I tried setting the priority of pd and pdgui to -10 and this seemed to help a bit. Maybe I need to adjust the buffers for ALSA to match the buffers of ASIO for ALL. which is set at 512bytes with a buffer offset of 4ms.

Thanks Bernardo
Charles Possibly so.
I wonder if I install the SB live if it will be autodetected. and the drivers are allready a part of the kernel or will I have to patch the kernel or something then reinstall all the audio software. At least I would determine if it is the soundcard or sound card drivers or not.
