Other Parts Discussed in Thread: TPA3112D1
Hi Team,
My customer is using the TLV320AIC3254 single-ended; LOL is fed into a TPA3112D1 RINP with a 1uF cap and they are not using the HP drivers. They are sometimes getting a pop noise at the beginning and end of audio. They have configured the driver to leave the DAC on and leave the midpoint powered all the time. Is there something else in the CODEC that can cause this random pop?
Here is their register dump:
