Original question:

PCM5142: DSP RAM program

PCM5142: no sound at output at different sample rates

Part Number: PCM5142

Hello.

In thread e2e.ti.com/.../3421600

I asked how to make PCM5142 output at 96 kHz and 192 kHz, because there is no sound at output. The only working audio stream is at 48 kHz.

As I was answered, I tried to enable different rates in PurePath Studio and got separate files (.cfg) for each rate to load to PCM5142. But these files have no differences, they are absolutely the same, identical. By now I have the same result: the only working audio stream is at 48 kHz. 96 kHz and 192 kHz rates input have no sound at the output, and it does not matter what file is loaded. The very same situation is with I2S output.

Could someone explain what I missed and correct my project (in attachement) to fix output at 96 kHz and 192 kHz?
