STA350BW ZIPPER NOISE OCCURS WHILE TUNING VOLUME

[RWENG]

I am using the STA350BW​. While I tried to change the output gains by writing register 0x07, a noise showed up. I found that it is something relative to DRC and when the DRC is enabled, ZCE seems not work.

How can I eliminate the zipper noise while tuning volume. Thanks.
