Hi Mark,
Please don't top post, reply in line with needed context. This allows readers to readily follow the flow of conversation and understand what you are talking about and also helps ensure that everything in the discussion is being addressed.
The SoC I2S block we currently have shares one clock and frame sync signal for both playback and capture stream, plus playback and capture can only have one master at a time. If we set playback and capture master at same time, it will have jitter on clock and FS.
I can't really parse what you're talking about here (perhaps some of that context would have helped...) but it doesn't seem to be the clocking of the I2S bus which would normally be what master and slave would be talking about. If it's something else perhaps the code needs to be clarified to make it clear that it's not talking about the bus.
