7.1 Surround Sound Test

All eight channels of a 7.1 system announce themselves in turn: front left, center, front right, side right, rear right, rear left, side left and the subwoofer. A switch fixes systems that swap the side and rear pairs.

This 7.1 surround sound test plays all eight channels one by one and announces each from its own position, so you can confirm that the side pair, the rear pair, the center and the subwoofer all work and are not swapped. The voice says "front left", "center", "front right", "side right", "rear right", "rear left" and "side left", and the subwoofer plays three low pulses. Because systems disagree on which pair is side and which is rear, a switch lets you swap them and test again. It also works as a 7.1 surround sound test online for virtual 7.1 gaming headsets: when the readout shows 8 outputs, each name should seem to come from a different place around your head.

How to run the 7.1 surround sound test

  1. Look at Outputs reachable. A 7.1 system or a virtual 7.1 headset should show 8.
  2. Press Check each speaker and answer for each channel. Walk to a speaker if you cannot tell which one spoke.
  3. If the side and rear names come from each other's speakers, turn on Swap side and rear pairs and run the check again.
  4. Use Noise and Play all to compare levels. All seven speakers should sound equally loud at your seat.
  5. Press Copy results to keep the verdict, including the swap setting you used.

What the results mean

Channel Where it should come from Common fault
Front left, front right Either side of the screen Swapped wires
Center Above or below the screen Set to None, so it plays from both fronts
Side left, side right Level with your ears, 90 to 110 degrees Swapped with the rears
Rear left, rear right Behind you, 135 to 150 degrees Silent: the amplifier channels are assigned elsewhere
Subwoofer The subwoofer only Plays from the fronts when the subwoofer is set to No
Outputs reachable 8 6 means 5.1, 2 means stereo

Side and rear speakers are swapped

In a 7.1 stream, channels five to eight carry the rear pair and the side pair, and not every system orders them the same way. Windows orders them rear then side, which is what this test plays by default. If "side left" comes from behind you, turn on Swap side and rear pairs: the test remembers the setting. When the swap is in your wiring, connect the side speakers to the Surround terminals and the rear speakers to Surround Back. Games use the same channel order, so get the wiring right rather than leaving the swap on.

The rear speakers are silent

  • The receiver uses those amplifier channels elsewhere. Many 7.1 and 9.2 receivers let you assign the surround back amplifiers to a second zone, to height speakers or to bi-amping the fronts. Set them to Surround Back in the speaker setup menu.
  • The receiver is set to 5.1. With Surround Back set to None, the rear channels fold into the sides.
  • Windows is set to 5.1. Run the Configure steps in the Sound control panel again and choose 7.1 Surround, with both the side and rear pairs ticked.
  • The signal is 5.1. If Outputs reachable shows 6, the browser and the system are sending six channels. Check the HDMI connection and the speaker setting.

A 7.1 headset sounds like stereo

Virtual 7.1 has to be switched on, and Windows has to send eight channels to it. If every name sounds as if it comes from between your ears, work through these:

  1. Open the headset's app, such as Razer Synapse, Logitech G HUB, SteelSeries GG or HyperX NGENUITY, and turn on its surround or spatial setting.
  2. Make sure the headset's 7.1 device is the default output. Some headsets add a second device just for surround.
  3. Or use Windows: open Settings, then System, then Sound, select the headset, and set Spatial audio to Windows Sonic for Headphones.
  4. Reload this page and check that the readout shows 8 outputs, then run the check again.

Even when it works, virtual surround is better at left and right than at front and back. Sides and rears that sound alike are normal, which is why the spatial audio test headphones quiz is a useful second check.

7.1 from a PC or a console over HDMI

A computer sends 7.1 as eight channels of PCM, which needs HDMI into the receiver or an eARC connection. Optical and ARC carry only two channels of plain audio. On an Xbox, open Settings, then General, then Volume and audio output, and choose 7.1 uncompressed for HDMI audio. On a PlayStation 5, choose Linear PCM under the audio output format setting. The receiver's display should show PCM 7.1 or a multichannel signal during the test.

Using the 7.1 test file

Open Test files and download the 8 channel FLAC. It announces the format, then each speaker in the same order as the test here, with three noise bursts after each name, and ends with the subwoofer channel. Play it in VLC or the Windows Media Player app on a computer set to 7.1, or from a USB stick on a receiver that reads FLAC. For a 5.1 system, the 5.1 surround sound test has a 6 channel file and an AC-3 version.

What the 7.1 test cannot do

The browser reaches only the channels your system offers, and it cannot detect where a sound came from in your room, so the result relies on your answers. It does not send height channels: those need a Dolby Atmos or DTS:X source, which the dolby atmos test explains. It cannot set speaker distances or levels: use the receiver's calibration microphone for that, then the subwoofer tester to check the crossover and phase.

7.1 surround test questions

How do I test 7.1 surround sound on my PC?

Set Windows to 7.1 Surround with the Configure button in the Sound control panel, reload this page and check that Outputs reachable shows 8. Then press Check each speaker. Each of the seven speakers should say its own name and the subwoofer should pulse.

Why are my side and rear speakers swapped?

Systems number the two back pairs differently. If "side left" plays from your rear left speaker, turn on Swap side and rear pairs under the volume control. If the swap is in the wiring, move the wires to the Surround and Surround Back terminals instead.

How do I know if my 7.1 headset is working?

Turn on the headset's virtual surround in its app or in Windows, choose 7.1 here and check that the readout shows 8 outputs. Each name should seem to come from a different direction around you. If every name sits between your ears, the headset is in stereo mode.

Is virtual 7.1 as good as real speakers?

No. Virtual surround uses a generic model of a head and ears, so left and right are clear but front and back often blur. The 3d audio test has a quiz that shows how well it works for you.

Can I download a 7.1 surround sound test file?

Yes. Open Test files for an 8 channel FLAC file that announces each speaker and plays noise from it. It plays in VLC, the Windows Media Player app and on receivers that play files from USB.
