What is the expected behavior?

When running the A2DP Sink example project, I should not be able to hear clicks and pops, ever.

What is the actual behavior?

When running the A2DP Sink example project, audio is fine, except when a pure sine wave is input.
For some reason, clicks and pops are exhibited, but strangely, only for pure sine waves (of any frequency).
This is evident for both the internal DAC output, and for external DAC via I2S.

Steps to reproduce.

  1. Build and run A2DP Sink example in either internal DAC output, or external I2S mode (it should not make a difference).
  2. Input a clean sine wave via Bluetooth A2DP, of any frequency. The important part is that it is a single frequency. If the signal has more than one spectral component, the issue cannot be reproduced.
  3. Listen to the signal, and hear consistent pops and clicks on playing, and then random thereafter.

This has been verified on both a devkit FireBeetle ESP32, and a custom board.
