Jack does not run correctly on the 8738. I first saw this on 2.6.12-gentoo-r10 so I updated to 2.6.14-rc5-rt5 and see the same problem. The problem is independent of JAck timings.

Does it work any better at 48000Hz? Any improvement with ALSA 1.0.11? ---------------------------------------------------------------------- Mark Knecht - 05-28-06 15:12 ---------------------------------------------------------------------- Sorry, but after 8 months of waiting for any response on this problem the machine no longer even runs Linux so I cannot test with newer Alsa. It's no longer an isse for me but I cannot say it's fixed.
