Hi, Gal

We are passing video and audio in I2S: sampling freq - 48k, Word length - 16bits, via the next 4 lines MCLK, SCK, LRCLK , I2S-0. The signals in the lines are described in the attached files scope_1.bmp and scope_2.bmp. As a result we received in the HDMI output - Screen good video but no audio. We connected the HDMI output to audio analyzer and we received a result that described in the attached file DSCN0570.JPG. I attached also my dump registers.
