Ok,
I'm not sure how to handle this correctly.
Magician needs stereo S16_LE input data from alsa, DAIFMT_DSP_A on the wire with a frame size of 16 bit (one frame for each channel) and thus 2-byte DMA transfers to the FIFO (currently called 'mono' DMA params). Zylonite's current code uses 32 bit frame size and 4-byte DMA transfers to emulate I2S (S16_LE,stereo). Network mode seems to work, so it could be changed to use two 16 bit slots instead with 2-byte DMA transfers (which would make Magician happy). But... Daniel's board needs very strange settings because network mode doesn't work, so I guess he can't use 2-byte DMA transfers. Is that correct?
If we can't find a way to have all machines use the mono DMA params, there has to be some kind of interface to set the width of the data in the FIFO independently from the Alsa format. How should that interface look like?
