Glitch noise is heard when playing low frequencies
I am using two amplifiers, TAS5822M and SN005807, and glitch noise is heard during frequency sweep (45~52Hz, 115~125Hz) or when playing tracks with strong bass.
It is noticeable when boosting the low range (60Hz) in the EQ, and noise can also be heard in the EVM. (occurs even at low volume)
We would like to request guidance on areas that require review or adjustments that can be made, such as resister settings.

Could you please have a try with below script, after start up and initialization?

After applying the above script, the noise disappeared.
Are there any areas that require additional review or adjustment after application?

The side effect for these codes is the idle noise level will a little raise, maybe increase around 30uV.

Try using smallest Analog Gain settings according to your target output power, to have minimum noise.
