Symptoms

  • Calls sound muffled or silent through the watch
  • Voice assistant doesn't hear you
  • No sound from notifications or alarms
  • Other person can't hear you on watch calls

Likely causes

  • CommonDebris or moisture blocking the speaker or mic portLint, sweat, and water can clog the small grille openings.
  • CommonVolume or mute setting turned down or onIt's easy to accidentally mute or lower watch call volume.
  • PossibleBluetooth audio routed to another deviceIf paired to earbuds too, audio may default there instead of the watch.
  • Less commonSoftware bug after an updateAudio routing bugs occasionally appear in firmware updates.

What to do

  1. Check the watch isn't muted and volume is turned up in settings.
  2. Inspect the speaker and microphone ports for visible lint, dirt, or moisture and gently clean with a soft dry brush.
  3. Run the water-eject feature if the watch was recently wet, since trapped water muffles sound.
  4. Check if other Bluetooth audio devices are connected and disconnect them to force audio to the watch.
  5. Restart the watch.
  6. Update the watch's firmware to the latest version.

Tools and parts

  • Soft dry brush or toothbrush

When to call a pro

If audio stays dead or muffled after cleaning and a restart, the speaker or microphone hardware itself may need professional repair.
