Depending on how the DMA and so on is done you can sometimes still do it
on the CPU side by lying to the CPU about the data format (eg, tell it
that two 16 bit samples are actually a 32 bit one) though it gets messy
for I2S since you need to be able to gather all the left samples and all
the right samples. Though given that your CODEC doesn't support it it's
still all moot anyway as you say.
