Well, I don't see anything wrong, maybe it has something to do with the fact
that the Midiman Delta 66 is an advanced multichannel soundcard?
Since you mentioned developing for ALSA: the current ALSA development is done
in the 0.9.x beta series. That is also the basis for the merge of ALSA in the
2.5.y development kernels. From lurking on the alsa-devel list I understand the
0.9 API differs considerably from the 0.5 one.
So I think it would be best to use ALSA 0.9.x. Btw, IIRC several people are
using the Midiman Delta 66 succesfully. Good luck!
