TPA3138D2: Input Voltage

Part Number: TPA3138D2

Hi Team, 

We would like to ask for your assistance with our customer's inquiry.

Whenever I send an audio signal to the board, I don't get an audio output unless I toggle the input power off and then on again.  After I power cycle the board I am able to get audio output from the board for a short while before it shuts off again.  I also ordered the development kit for this board and noticed a similar issue.  I would appreciate some input to determine why this is happening.

Hoping for your kind response.

Thank you,

Regards,

Mark
