Hi 

 When  TAS3251EVM is setten to BTL mode and connect to PPC3 in 2.0 mode and standard processing 2.0 96K audio mode. I only connnet the rigth channel with a speaker.

When i play music in the audio player at the top of PPC3, there is no music from the speaker. I use the hardware check process and appear below problem, can you help to check ? And my EVM is setten as below picture. 

  • Hi Aggil,

    Are you using the USB as the source for your input signal? Based on the image it appears so.

  • Hi Aggil,

    Please also double check the EVM configuration(like jumpers, switches...) with the quick start guide on EVM User's guide.

    Hi Aggil,

    Did you also press the input button to make sure that it's on USB? Based on the picture you sent it doesn't appear so.
