Maybe I misunderstood but shouldn't there be some sort of verification that the codecs can use the same number of slots between playback and capture if they share the same LRCLK/FS? e.g. it's not uncommon to have 4 mic capture and 2 ch playback. If the capture and playback is handled by different chips you'd still need to maintain some level of consistency.
Yes, this was my point about it being hard to work out what's going on with regard to things being shared.
