Headphone, speaker and multiroom-audio troubleshooting

Headphones, soundbars and multiroom speakers that will not pair, drop out, lose sound or fail an update, covering AirPods, Bose and Sonos.

Audio faults tend to be a connection, a setting or a paired-device problem rather than a broken speaker. A Bluetooth speaker that pairs but plays no sound has usually been paired but not chosen as the output, so check the phone's audio output, volume on both devices and any other device it is still connected to. One earbud that is quieter than the other is often dirt in the mesh or a fit problem, and a charging case that will not charge needs its contacts and cable cleaned. Multiroom systems such as Sonos drop out when the Wi-Fi is weak or when rooms are grouped across different networks, and a soundbar's wireless subwoofer usually needs to be re-paired by holding its connect button.

Diagnose the exact device problem
AirPods · charging case

AirPods case will not charge

A case can fail to charge because of cable/adapter, port debris, wireless alignment, temperature or battery damage. Test wired charging from known power before resetting AirPods.

Open record
Bluetooth audio · routing

Bluetooth speaker pairs but no sound plays

Pairing confirms a control link, but audio may still route to another output, use the wrong profile or be muted in the source app/device.

Open record
AirPods · audio balance

One AirPod is much quieter than the other

Uneven volume usually comes from grille blockage, ear fit, balance settings, charge/contact or one damaged driver. Compare ears and audio balance before resetting.

Open record
Sonos · grouped playback

Sonos audio cuts out only when rooms are grouped

Group-only dropouts point toward wireless capacity, interference, a weak coordinator or network topology more than the music service itself.

Open record
Sonos · discovery

Sonos speaker disappeared from the app

A missing Sonos room can be offline, on another household/network, wired incorrectly or blocked by network isolation. Do not factory-reset it before checking its status light and network.

Open record

Restart the source and the speaker, forget and re-pair the Bluetooth device, and update the app and firmware. Keep the speaker away from metal and other 2.4 GHz devices. For soundbars on HDMI, use the port marked ARC or eARC. Model-specific problems for Bose, Sonos and AirPods are on the brand pages, including firmware that will not finish and sound that is delayed behind the picture.

Why do my Bluetooth speakers pair but play no sound?

The phone or computer may still be sending sound to another output. Choose the speaker as the output device and check both volumes.

Why is one AirPod quieter than the other?

Earwax or debris in the mesh is the most common reason. Clean it gently with a dry soft brush, then check the balance setting under Accessibility.
