What sound it plays

  • The 5.1 channel buttons appear after the first sound, and only when the browser sees 6 or more output channels.

Common questions

How do I know if my earbuds are swapped?

If pressing left plays in your right ear, they're swapped. Check how you're wearing them and the output device first.

Sound only comes from one side.

If 'Both' also plays on one side only, suspect the cable, the jack or the device itself. Plug into another device to compare.

I pressed left but hear it on both sides.

Windows 'Mono audio' may be on, or the speaker may be a single (mono) speaker.

Can I test 5.1 surround?

Per-channel buttons show up only when the browser sees 6 or more output channels. With 2 channels you can check left and right only.

I want to check my mic too.

The mic test shows your input level and lets you record and listen back.
