Hi Expert,
Used the EVM and datasheet setting, it can get a big pop when set the unmute, whatever change the P1 0x14, can't get the good result.
1. slau472.pdf page50 4.0.8 setting.
2. Adjust the P1 0x14.

# Assert Software reset (P0, R1, D0=1)
W 30 01 01
# Page Switch to Page 1
W 30 00 01
# LDO output programmed as 1.8V and Level shifters powered up. (P1, R2, D5-D4=00, D3=0)
W 30 02 00
# Master Reference Powered on (P1, R1, D4=1)
W 30 01 10
# Enable AINL and AINR (P1, R9, D1-D0=11)
w 30 09 03
# AINL/R to HP driver not via Mixer P (P1, R12, D1-D0=11)
w 30 0C 03
# HP Voulme, 0dB Gain (P1, R22, D6-D0=0000000)
W 30 16 00
# Not enable HP Out Mixer, AINL Voulme, 0dB Gain (P1, R24, D7=0, D6-D0=0000000)
W 30 18 00
# Enable AINL and AINR and Power up HP (P1, R9, D5=1, D1-D0=11)
w 30 09 23
# Unmute HP with 0dB gain (P1, R16, D4=1)

It can reduce the pop level, but still can hear that. Whatever how to adjust it, we can get the sharp voltage to DC offset, how to adjust it to smooth? Can you provide the EVM setting to me? Or it's IC limitation? Thanks!
