It took a long time, but I found the bug!!!

I just forgot to send the sync-samples to the card :-).

Ok, you can get the newest version of the driver from

ftp://ftp.tnt.uni-hannover.de/pub/misc/alsa-za2/

Only output is tested so far. But this should work with 16bit, stereo,
20kHz-60kHz. You shouldn't pause the driver as resyncing probably does
not work so far. Another problem is DMA. It seems that the DMA starts
running directly after enabling in snd_dma_programm although it should
start after setting the bits in the ZA2-command-register. I don't know
why. If you notice switched left and right channels comment out
enable_dma in snd_dma_programm in kernel/isadma.c. In my opinion it's
a better idea to always let the driver enable the dma at the right
point. Maybe this can be changed in ALSA (Jaroslav?).
