STM32H573I-DK USB audio output cutting in and out

zachwilliams · ‎2024-12-01

I've flashed the board with the X-CUBE-Audio-Kit LiveTune firmware and then used the CLI in the LiveTune web app to set the sample rate to option 6: 06:Mic:onboard: Out: 48KHz 2Ch In: 48KHz 2Ch-1Mic Duration:1ms: ID_02480248onb01FFFFFF

When I playback audio on my Mac, audio is coming out but it is playing back as if there is a tremolo effect on the audio. It's cutting in and out in volume probably 2 to 3 times per second. Is there something in the configuration I'm supposed to change to fix this? I've loaded up the pop equalizer LiveTune configuration. I have attached both the firmware and the .livetune file.

Any thoughts from anyone?

Hi @zachwilliams

Would you share a record that could be tested directly over USB. I have forwarded you inquiry to our dedicated expert as I couldn't reproduce the issue on my end using your HEX. Did you try to playback your audio on different OS? Windows or linux?
