am3517 audio issue

Other Parts Discussed in Thread: AM3517, TLV320AIC23B

Dear all,

I'm trying to make the audio out working on AM3517 evm board ( audio codec is TLV320AIC23BPW). I set audio codec in master device, usb mode,CLIKIN=CLIKOUT=MCLK, set sampling rates by writing TLV320AIC23B register:0001000  according to  TLV320AIC23B Data  Manual. I try  to play 48kHz,44,1kHZ,96KHZ stereo wave file.But  my headphone only have left channel output.

Another question, I am unable to  control line out volume(R & L), there is no any change though i wrote  line out gain the max value.

Can you please help me?

regards,

fang
