Most useful causes to check

Wrong output

The operating system may be sending the browser to a monitor, dock, headset or disconnected Bluetooth device.

Muted path

Browser tab, site, app mixer, system, device and hardware controls can each mute independently.

Permission or policy

Managed devices and strict browser settings can block playback until a user interacts with the page.

Repair steps by system

Interfaces change between system versions. Use the setting names as landmarks, then return to the same test.

Windows

  1. Open Settings → System → Sound and verify input and output devices.
  2. Open Volume mixer and confirm the browser is not muted or routed elsewhere.
  3. Disable enhancements temporarily and retest.

macOS

  1. Open System Settings → Sound and verify the selected output.
  2. Check output volume and the left/right balance control.
  3. Reconnect the device, then quit and reopen the browser if routing is stale.

iPhone and iPad

  1. Open Control Center and check the current AirPlay output.
  2. Open Settings → Accessibility → Audio & Visual and review mono audio and balance.
  3. Disconnect and reconnect wired or Bluetooth audio.

Android

  1. Use the media output switcher to choose the intended device.
  2. Check media volume separately from ring and alarm volume.
  3. Review Accessibility audio balance and mono settings, then reconnect the device.

Verify the repair

Change one setting or connection, then repeat the same controlled signal. If the symptom follows the hardware to another source, physical service becomes more likely.
