Default nobsound mo-gu drok f900 dual tpa3110 amp

Cheap and good sounding amp.
I couldn't find any pictures of the inside on the internet.
My second order came in damaged, so i could take some pictures of the printed circuit.

What are the markings the chip on the lower-right hidden by the wires? My guess is that it is the Bluetooth DAC/SoC, Which probably makes it responsible for the annoying voiceover.

removing the case:

remove 4 screws behind the sticker on the speaker terminal side.
unscrew the pot meter.
slide out the amp board.

The other side looks the same, but you don't have to remove those ( photo )

Does anyone find a way to disable these annoying startup/bluetooth sounds?

What Bluetooth Chip is used in this amp?
The cable on these pics is covering the model number
