Hello,

 

I have been working on ADAU1373 codec, I have ALC working in digital PGA mode, but the problem is there some issue with some of the players (video uploaded on facebook) not able to play the audio properly (VLC, WMP.. can play it fine).

If I disable the ALC and the video plays fine on (facebook). For this reason I want to try the Analog PGA for ALC

 

If I enable the analog PGA for ALC, I see that there is different levels for left and right channel, but the levels are same when used with digital pga mode. Any hints why this could be happening ?

 

Cheers,
