TAS5825PEVM: Can NOT play sound with EVM.

Part Number: TAS5825PEVM
Other Parts Discussed in Thread: TAS5825P, TAS5782MEVM, TAS5825MEVM

12V is supplied to PVDD, and usb is connect between EVM and PC.

Amp output pin connect to 2 speakers.

PC can recognize and select the UAC speaker.

PPC3 shows TAS5825P Connected

But I play music in PC, speaker is always silent.

Is there something I did NOT noticed or missed?

Is there any step by step video for reference?

PS: TAS5782MEVM and TAS5825MEVM can be controlled by PPC3, and play sounds from USB normally.
