Sound Issues

This page provides instructions for resolving sound problems where a computer produces no audio,
distorted audio, or audio from the wrong output device. These instructions apply to both built-in
speakers and external audio devices on Windows computers.

Symptoms

  • No sound from speakers or headphones
  • Distorted or crackling audio
  • Audio plays from the wrong device
  • Volume icon missing from taskbar
  • Bluetooth audio not connecting or cutting out
  • USB audio device not detected

Root Cause (Plain Language)

Sound output requires functioning audio drivers, correct device settings, working hardware connections,
and proper Windows configuration. When any of these components fail, sound stops working or becomes
distorted.

Sound problems occur due to:

  • Incorrect output device selected
  • Loose or faulty audio cables
  • Disabled audio devices
  • Corrupted or outdated audio drivers
  • Bluetooth pairing issues
  • Windows audio services not running

This guide addresses both hardware connection issues and software-related audio failures.

Step-by-Step Instructions

Step 1: Check Volume and Mute Settings

  1. Click the speaker icon in the taskbar.
  2. Ensure volume is above 20%.

  2. Scroll to More sound settings.
  3. Open the Playback tab.
  4. Right-click inside the list and enable Show Disabled Devices.
  5. Right-click your device and select Enable.

After enabling the device, play a sound to test.

If sound works normally, proceed to Verification Steps. If the issue continues, proceed to Step 7.

Step 7: Restart Windows Audio Service

The Windows Audio service controls sound output. Restarting it can resolve audio problems.

  1. Press Win + R, type services.msc, and press Enter.
  2. Scroll down and find Windows Audio.
  3. Right-click it and select Restart.
  4. Repeat for Windows Audio Endpoint Builder.
