Noise Problem in the Audio Output

Other Parts Discussed in Thread: OMAP3530, TLV320ADC3101, TLV320DAC32

Hi all,

I am working on the audio testing. I dont want to confuse you telling more story which is not needed.So i have mentioned the devices whatever i am using.

Processor - OMAP3530

ADC - TLV320ADC3101

DAC-TLV320DAC32

Mcbsp- MCBSP2

Mode - TDM

Input - 2 channels (Mic1-left Channel Mic2- Right Channel)

output - Head phone

 Issue - I am feeding the 2 mono input to ADC from PC(customized cable for sterio to 2 mono).Almost i have acheived to get the Audio output.But  I am getting some noisy output in the head phone. i have tried with some junk data which will produce the sound wihout any noise. So it seems there is no problem in the DAC which means in output side. So the problem might be in the ADC (Audio input) side. it seems some data is missing to reach the ADC or DAC. there are some registers like offset1,offset2. i given them as zero.

if anyone  of you working in the TLV320ADC3101 and TLV320DAC32 plz can you help me to solve this issue.

Thanks
