Technical Overview

This diagnostic tool uses the Web Audio API to generate mathematically pure sine waves. By panning these signals, we can isolate individual hardware drivers to ensure your wiring and software configurations are correct.

Common Fixes

  • Ensure your hardware volume is above 20%.
  • Check for "Audio Enhancement" software that might be forcing mono output.
  • Unplug and re-seat 3.5mm jacks; half-plugged jacks often result in single-channel audio.
  • Ensure the correct output device is selected in your OS sound settings.
