Brian,

The comments I was remembering are in the following two posts on the
Linux Audio User mailing list :

http://lists.linuxaudio.org/pipermail/linux-audio-user/2009-November/064820.html
http://lists.linuxaudio.org/pipermail/linux-audio-user/2009-November/064828.html

I don't have the expertise to evaluate them, but there are enough
knowledgeable people on LAU that I would have expected the comments to
be shot down if they were out of line (they weren't).

I noticed in those posts that they regard rtprio as the critical
setting - should this be included in Studio Controls ?
