Hallo,

I have a driver for Zefiro Acoustics ZA2 and I would like to integrate
it into ALSA. I read the description to ALSA-kernel-library, but I'm
not quite sure where to start. The ZA2 uses a DSP CS4920. But it's not
acessable directly from the PC. Probably a module for the CS4920 does
not make sence. The ZA2 uses ISA-DMA for transferring data from/to the
PC. How does the ALSA-kernel-library support ISA-DMA beyond those two
functions snd_dma_program and snd_dma_residue? Which devices must be
created? The ZA2 has a digital I/O-interface only. Probably a mixer
device does not make sence. MIDI is not available. 

Maybe somebody can give me some hints, where to start.


Thanks a lot,

Martin Pahl
