I'm using ADV7511 connected to TMS320DM368 SoC. I encountered problem with detecting sound format. I send 16bit per channel audio signal on I2S0. There is SCLK,LRCLK, and I2S0 data connected to chip. MCLK is connected to ground. I2S signal send by SOC looks good. The problem is that ADV detects it as 64bit per LRCLK period instead of 32bit. I set up all registers needs to be set based on PROGRAMMING GUIDE. HD video works well for me (1080P30), I suppose until it detect valid signal width, it couldn't hear any sound.
Thanks in advance !
