Hi Geraldo, Mark,

Hi Sugar!

could you share your I2S and HDMI register dump to me to dig out the root cause.

I ended up sorting it out on my own. HDMI AudioSample Register aud_conf2 must be set to 0x4. This sets insert_pcuv bit and solves the extreme clipping problem.

I'll post a patch later.

Thank you, Geraldo Nascimento
