Yes, there's some question if a multi-channel I2S setup is going to be
all the left channels then all the right channels, have multiple data

something else.  Usually it's safer to use a DSP mode for those.

Please fix your mail client to word wrap within paragraphs at something
substantially less than 80 columns.  Doing this makes your messages much
easier to read and reply to.
