Is that a intel-hda card? If so, try 3 periods per buffer. It seems
those types of "soundcards"(*) don't work with anything else. You might
also benefit from a slightly smaller frames / period, like 512.

The driver flags mentioned by Ivica Ico Bukvic (position_fix=1) is also
a good idea. My intel-hda "soundcard" only produces distortion without
it.

The alsa driver should be better in the performance sense. You should
try different options for jack until you get it right.
