How to understand your result

Looks good: Both left and right channels output distinct, unreversed stereo sound.
Check this: Sound played from both sides during single channel test (check OS mono audio setting).

Troubleshooting: what to try next

  • Check Windows/macOS Accessibility settings to ensure 'Mono Audio' is disabled.
  • Inspect 3.5mm jack seating.

What this test cannot tell you
