TLV320AIC26: No audio output

Part Number: TLV320AIC26

Hi Sir,

One of our projects uses TLV320AIC26 to convert PCM to speaker audio, but no audio output is detected in HPR and HPL pin.  

The hardware schematic circuit is as follows:

At present, we have detected that PCM IN has data. At this time, BCLK=256K, LRCK=8K, CLK=12M. POWER and RESET are at high level when working, and reset will be pulled high after power is turned on and held at high level for 500ms;

When disconnect HPR, HPL related circuit for testing, no signal output also did not detected at HPR and HPL pins.

We tried to write some parameters, but the read value of some registers is not consistent with the written value. The following are our initialization code and read back log (some registers read back abnormally).

Can u help analyze the cause of this problem?

Thanks,

Best Regards
