According the datasheet of the Tripath TA2022 pin3 VN10GND should be connected to PGND also earth because of the screen/shielding of the chip.
The board has a grounding system where the following parts are ground together:
- 0 of the symmetrical ac input
- the "-" of the unbalanced input
- the "-" of the speaker terminals output
What's best practice to ground these to mains earth?
