How to Tune a Sonos Arc Ultra with Trueplay

Use the Sonos app to tune Arc Ultra with Quick tuning on iOS or Android, or Advanced tuning on a supported iOS device.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To tune a Sonos Arc Ultra, open the Sonos app and select Settings → Your System → Arc Ultra → Sound → Trueplay → Trueplay Tuning. Android users get Quick tuning; on iOS, you can choose Quick or Advanced tuning. Quick tuning uses the Arc Ultra’s built-in microphones, while Advanced tuning uses the iPhone or iPad microphone.

Choose Quick or Advanced tuning

Method Available on Microphone used What to know
Quick tuning iOS and Android The Arc Ultra’s built-in microphones The microphone switch must be on for the Arc Ultra and any other participating Sonos products. It works with the Arc Ultra alone or in a home theater setup with surrounds and a Sub.
Advanced tuning Supported iOS devices only The iOS device’s microphone Requires moving around the listening room. Sonos describes it as the more precise process; some iOS devices are unsupported.

Sonos says Trueplay measures how sound reflects around the room and adjusts the Sonos product accordingly. See Sonos’s Arc Ultra Trueplay instructions for the current setup details and supported-device information.

Run Trueplay tuning

  1. Make sure your setup is ready. Confirm the Arc Ultra and any other Sonos products you want tuned are set up and available in the Sonos app.
  2. Enable the microphones for Quick tuning. Check that the microphone switch is on for every participating product. The Arc Ultra’s built-in microphones are used for this method.
  3. Open the tuning controls. In the Sonos app, go to Settings → Your System, select Arc Ultra, then choose Sound → Trueplay → Trueplay Tuning.
  4. Select a method if prompted. On iOS, choose Quick tuning or Advanced tuning. On Android, the app uses Quick tuning. Follow the instructions displayed in the app.
  5. For Advanced tuning, move through the room as directed. Keep the room as quiet as practical. Move the iOS device smoothly from head to waist, covering as much of the room as possible. Do not change the speaker volume while the tuning sound plays. Sonos says an advanced room-tuning session takes about three minutes.

Improve a failed or disappointing tune

If tuning fails

  • For an iOS tune, check that both the iOS device and speaker remain connected to Wi-Fi.
  • Reduce background noise; noise can cause tuning errors.
  • Close other apps that are using the iOS microphone, and disconnect Bluetooth headphones or speakers if they interfere.
  • If you are using a newly released iOS device, it may not yet have a supported tuning profile.

See Sonos’s troubleshooting guidance for Trueplay errors for further checks.

If the sound is not what you want

Room acoustics and speaker placement can lead Trueplay to boost or reduce frequencies you would rather hear differently. For Advanced tuning, try reducing noise, covering more of the room with smooth movements, and moving the device more slowly; keep the volume unchanged during the tuning sound. You can adjust EQ in the app or toggle Trueplay off temporarily to compare the result with the tuning adjustments disabled. Sonos explains the adjustment controls in its EQ settings guide.
