Missing info in manual

The RK3128 manual is missing the pin outs for the 8-channel I2S device. Chapter 47 tells all about how to use the 8-ch devices, but which pins does it come out on? That info is missing from the manual. 8-ch is I2S1, the pin out info for I2S0 is there.

I second this request.

Thx

I don't believe the 8-ch I2S is externally accessible. Instead it is internally wired to the HDMI output.

But... there is nothing in the documentation supporting this. It is just my guess from reading the audio driver source code.
