  • Hi Yuki,

               1. Pls confirm you PPC3 and TAS5825M version is the latest.

               2. Check the TI audio drive is normal(When plug in EVM to computer, the sound playback device should choose TI USB Audio)

             3.   Suggest to use TAS5825MEVM rather than TAS5825MEVM-SB for debug. But I think your issue isn't a big problem since TAS5825MEVM-SB may not have SDOUT back. You can try to download the program by entering tuning interface to check whether the amp can work.
