Hello,
The RK3288 can provide up to 4 I2S outputs. If you look at page 12 of the Firefly board schematics you can see that only I2S_SDO0 is connected to the processor pins. So having 4 channels or more would require these channels to be interleaved on a single output stream. I don't know if this is possible, or even if it is implemented within the audio driver. I've just began to study the i2s/pcm manual chapter and the way it works is not yet clear in my mind.
Maybe Linux rock chip specialists could answer that?
Thx
