TLV320AIC3263: Audio Record with Multiple Analog Microphone

Efe AKALIN
Prodigy 10 points

Part Number: TLV320AIC3263

Tool/software:

Hi,

Im using TLV320AIC3263 codec on my system. My aim is to record audio from two seperate analog microphones simultaneously using single SAI interface.

Mic1 -> INxL

Mic2 -> INyR 

ADC Processing block -> PRB_9 (Streo Mode)

CM1 Configuration ->  0.9V.  

PGAL P/M --> INxL / CM1

PGAR P/M --> INyR / CM1

Im able to record audio successfully from the microphone on left ADC channel but cannot record from right channel fully ( Volume is so low for every ADC gain and PGA gain configuration) . 

I've verified my hardware and everything seems to be okey , what am I mising for the codec configuration ?  

Thanks in advance.
