Steps

Goal: Check volume, output selection, cables, and driver—then isolate the cause.

Check volume and output

Goal: Confirm the system volume is up and the correct output device is selected.

  • Check the system volume in the taskbar (Windows) or menu bar (Mac). Check physical volume knobs on speakers.
  • Open Sound settings. Under Output, confirm the correct device is selected—built-in speakers, external speakers, USB audio, or Bluetooth.
  • Good: Volume up and correct output selected. Proceed to Verify cables.
  • Bad: Volume was low or wrong output—fix and test.

Verify cables and connections

Goal: Confirm wired connections are firm.

  • For 3.5 mm: check the jack is fully inserted in the green port (speakers), not pink (mic).
  • For USB speakers: confirm the USB cable is firmly connected.
  • For HDMI audio: confirm the display is set to use that input.
  • Good: Cables are firm. Proceed to Driver.
  • Bad: Loose connection—reconnect firmly and test.

Update driver (Windows)

Goal: Update the audio driver when sound does not work in any app.

  • Play video or music in a different app. If sound works there, the problem is the original app.
  • If it does not work in any app: Device Manager, expand Sound, video and game controllers. Right-click the audio device, Update driver, Search automatically. Restart if prompted.
  • If the device has a yellow warning: right-click, Uninstall device, restart. Windows will reinstall.
  • Good: The speakers work. You are done.
  • Bad: The speakers do not appear or still have a yellow warning—see When to get help.

When to get help

Contact the device manufacturer or IT if:

  • The speakers do not appear in Sound settings.
  • The audio device has a yellow warning in Device Manager after updating the driver.
  • Sound fails in all apps.

Provide device model and OS version.

Verification

  • Sound plays from the speakers when you play video or music.
  • The correct output device is selected when you have multiple options.
  • No yellow warning on the audio device in Device Manager.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Volume and output Check volume and mute; confirm the correct output device is selected.
  2. Cables and connections Verify 3.5 mm, USB, or HDMI cables are firmly connected.
  3. Test in another app Isolate app vs system—play in browser or media player.
  4. Update driver Device Manager, Update driver, Search automatically.
  5. Call support Speakers not in Sound settings, yellow warning, or all steps failed.
