Are All Your Surround Sound Channels Working?

Play test tones through each surround sound channel individually to verify your 5.1 speaker configuration. Identify silent, swapped, or misconfigured channels instantly. 7.1 support is coming soon.

Tests each discrete audio channel in your 5.1 surround sound setup — front left, front right, center, subwoofer (LFE), rear left, and rear right.

Over 30% of surround sound setups have at least one misconfigured channel, often the center or rear speakers being swapped.

What Do Your Results Mean?

Result Range Meaning
Good All channels produce sound from the correct speaker position Your surround sound system is properly configured and all speakers are functioning correctly.
Warning Some channels play from unexpected speaker positions Speaker wiring or software channel mapping is incorrect. Check your audio driver settings and physical speaker connections.
Poor One or more channels produce no sound at all A speaker may be disconnected, blown, or your system is not outputting true surround sound. Verify your audio output is set to multichannel in OS settings.

Common Issues & Solutions

All audio plays from only two speakers instead of surround channels

Your system may be set to stereo output. Go to your OS sound settings and change the speaker configuration to 5.1 or 7.1 surround. Some browsers downmix to stereo by default.

Rear speakers are silent during the test

Check that rear speaker cables are connected to the correct ports on your receiver or sound card. In Windows, run the speaker setup wizard from Sound settings to verify channel assignment.

Left and right channels seem swapped

The speaker wire connections are likely reversed. Swap the left and right speaker cables at the amplifier or sound card output.

Subwoofer (LFE) channel produces no bass

Verify your subwoofer is powered on and the LFE cable is connected. Check that the crossover frequency is set correctly (typically 80-120 Hz) in your receiver settings.

Frequently Asked Questions

How do I test surround sound in my browser?

Click each channel button (FL, FR, C, LFE, RL, RR) to play a test tone through that specific speaker. Listen to confirm sound comes from the correct physical speaker position. The test uses the Web Audio API to route audio to individual channels.

Does this test work with virtual surround sound headphones?

Yes, but results depend on your headphone software. Virtual surround (e.g., Dolby Atmos for Headphones, Windows Sonic) simulates positional audio in stereo headphones. You should hear each channel as a distinct spatial position around your head rather than from physical speakers.

Why does my browser only output stereo even though I have a 5.1 system?

Most browsers default to stereo output for compatibility. On Windows, ensure your default audio device is set to 5.1 or 7.1 in Sound Control Panel. On macOS, use Audio MIDI Setup to configure multichannel output. Chrome and Edge generally support multichannel output when the OS is configured correctly.

What is the difference between 5.1 and 7.1 surround sound?

5.1 surround uses six channels: front left, front right, center, subwoofer (LFE), rear left, and rear right. 7.1 adds two side surround channels for more precise sound positioning. The '.1' refers to the low-frequency effects (subwoofer) channel, which carries bass frequencies below 120 Hz.
