Sonos Sub recalibration (no sound output)

<= Back

Run through the SUB’s audio calibration to make sure it’s at least playing the test tones for setup. You can do this from the Settings page of any controller.

Using a handheld controller:

1. Select Settings -> Room Settings.

2. Select the room that is associated with the SONOS SUB. It appears as Room (+SUB) on the Room Settings menu.

3. Select Advanced Audio -> Recalibrate SUB.

4. Follow the prompts to optimize your SUB’s performance.

Using the Sonos Controller for Mac or PC:

1. Select Manage -> Settings (PC) or Sonos -> Preferences (Mac).

2. Select Room Settings.

3. Select the room that is associated with the SONOS SUB. It appears as Room (+SUB) on the Room Settings menu.

4. Select the Basic tab, and then select Recalibrate SUB.

5. Follow the prompts to optimize your SUB’s performance. During the recalibration, the SUB will play a few test tones and ask you to pick adjust settings to your liking. Let me know if the test tone plays or if it does not.

This should finalize the sub calibration.
