Audio thru 40 pin connector


#1

I have connected PCM output from 40 pin connector of Hikey board (16,18,20 & 22 Pin) to our I2S board,however while playing audio thru Hikey board with Andorid OS init.I am not receiving any signals(tested with Oscilloscope) from those PCM pins.

Please let me know is there any thing I am missing to enable PCM audio output from Hikey board.

Thanks in Advance,
NY

Did you figure it out on how to get the audio from the header?
