Can anyone understand and help me with the PDF of the digital-analog chip WM8766? [Copy link]

Can anyone understand the PDF of the digital-analog chip WM8766? Because the remote control is broken, the 5-channel sound has become 3-channel, and the center and left and right channels do not sound. I found that the digital-analog chip WM8766 (pins 24, 25, and 26 are the center and left and right channels) has no audio output, but has a 2.5V voltage output. Can anyone understand the PDF and explain how to set the chip so that all 6 channels have sound?

Pin 7 has audio signal input, pins 21, 22, and 23 have sound output, and the three speakers will sound. Pin 1 is high level, and pins 3 and 4 have pulse signal input. I don't know how to set it. Thank you.

You don't have to care about how to set it up. Repair is not design. What you should judge is whether the chip is damaged.
