ADV7513 channel 7 & 8 audio problem

Hi,

I'm having issues with audio on the 7513. Enabling channel 5 and 7 at the same time causes a distorted mix of the two channels to be output on both 5 & 7. In this state, channels 1-5 break as well. Turning off either channel yields good audio on the other. Channels 6 & 8 have the same issue. I've verified that audio into the 7513 is working properly. I want to be able to use all eight audio channels, and have set all to active.

 

I am operating on a 256x supplied I2S MCLK, with 48 kHz sampling frequency

Video is 4:2:2 with separate syncs.

 

My audio initializations are as follows:

72 15 21

72 0A 01

72 0B 2E

72 0C 3C

72 73 07

72 76 1F

72 44 79

 

Thanks,

Varun
