If I'm reading rour post right, you're specifying 20 msec latency and getting about 22, which is OK, but I think you should be able to get lower latencies (i.e., I don't see that numbers like 21.9012 are too good to be true - those are typical Macintosh latencies but I think in linux you should be able to do much better.)

you are right - those numbers seem to be to good to be true. On the other hand I followed the instructions in the latency patch and don't know what could have been wrong.

Hmm - I'm getting latencies between 6 and 7 (Fedora 17, Core 7200, INTEL "HDA", latest Pd from git, but I think Pd 0.43 should do similar).

Hi Max,
Is it possible for you to test this same card in linux?
J
I wanted to do this, but I don't have a linux machine with firewire, so i can't test the ffado driver for the card. I wanted to try out the class compliant mode, but there is a bug in ALSA which prevents it to work. see http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28935.html I didn't wanted to get started recompiling the kernel for this. sorry. So in theory it should work, but only if you remove the bug in the ALSA part.
for the record i compared the on board intel card of the linux machine, the result is quite impressive, i don't think it can get any better:
