TAS5805MEVM: EVM board sound output not available(question speaker connection & Register map)

Prodigy 10 points

Part Number: TAS5805MEVM

Tool/software:

When playing through the audio player in PPC3, no sound output is made toward the EVM board. (USB connection is made between EVM board and PC, board connection is made within PPC3, and the selection of sound source playback device on PC is also selected as EVM board.)

1. When using  Systems, should the two input lines of the speaker be connected to out 1 and out 2 respectively as shown in the figure? (At this time, is it correct that the two pins of out 1 are shorted, and the two pins of out 2 are shorted?)
2. Share the register map set on the EVM board (three captured images) Please guide me on the part of the register that needs to be modified for sound output on the EVM board and how only that register can be modified through PPC3

    Please make sure in the PPC3, you are choosing Stereo2.0, or Mono1.0PBTL? Your picture shows the PBTL using. The connection should be the same as your choice.

    The register shows device works normally. So the problem should be the SDIN signal.

    Make sure choose XMOS on the board first.

    Then, check your computer Volume, choose TI USB, and not muted.
