This IC is part of a RTS intercom panel. Model KP-4016, used in broadcasting.
Getting garbled audio on the headset output.
Pretty sure it’s a audio amplifier of some type. Was able to trace some pins to the headset Left and Right output of the 5 pin XLR.
Tried to google the letters on the IC but no luck.
Pretty sure it’s something like this:

The markings are very similar to the MAX98357AETE+T Analog Devices audio amp.
