About this test

The speaker test plays a short sound on one channel at a time so you can confirm stereo is working: the left sound should come only from the left, the right only from the right, and centre from both equally. It quickly reveals a dead speaker, swapped wiring, a balance setting that is off or headphones in mono mode.

How to use this test

  1. Turn the volume down, then click Left.
  2. Click Right and Center and listen for where the sound comes from.
  3. Use Alternate to switch automatically while you adjust balance settings.

Frequently asked questions

Both sides play the same sound. Why?

Mono audio is turned on in accessibility settings, or the output device is mono. Check our left/right sound guide.

Can I test surround speakers?

Yes, use the Surround Sound Test for 5.1 and 7.1 systems.
