Fixing Sound or Audio Problems on Windows
If there is no sound on your Windows computer, the following steps might help. Follow the steps in order. Start with the first one and see if it helps. If it doesn’t, move on to the next step.
Step 1: Check Cables, Plugs, Jacks, Speaker and Headphone Connections
- Make Sure Everything is Plugged In: Check that your speakers or headphones are connected to your computer. If you’re using the built-in speakers, make sure they’re enabled in the BIOS or UEFI settings. For external audio devices, make sure they're charged, the cables are connected properly, the ports aren't damaged, and the device is turned on.
- Try Another Port: Try connecting your speaker or headphones to a different audio or USB port.
- Test on Another Device: Connect or pair the speaker or headphones to another device to confirm it works.
If this doesn’t help, continue to the next step.
Step 2: Check Sound Settings
If the audio is muted or the volume is too low, you might not hear anything from the speakers or audio device.
- Turn Up the Volume: Click the speaker icon on the taskbar and make sure the volume is up.
- Check Physical Volume: If you’re using headphones or external speakers, make sure their volume is turned up too.
- Check for Mute: Open the Volume Mixer by going to Start > Settings > System > Sound > Volume mixer. Make sure no apps are muted and that all volumes are set correctly.
If that didn’t help, continue to the next step.
Step 3: Check the Speaker Output Device
If there are multiple audio output devices to choose from and the wrong one is picked, you might not hear any sound from the speakers or headphones.
- Choose the Correct Output Device: Go to Start > Settings > System > Sound. Under Output, select the audio device you want to use. This will also make it the default device.
If choosing the correct audio output device didn’t help, continue to the next step.
Step 4: Fix Audio Drivers
Updating audio drivers or rolling back drivers can often fix audio playback issues caused by corrupt audio drivers.
Update Audio Drivers using SupportAssist
Dell's SupportAssist tool automatically scans your Dell computer, looks for driver updates, and installs them:
- Search for and open SupportAssist.
- On the Home tab, select Update software.
- Select Start to check for driver updates and follow the instructions.
- Alternatively, go to Dell Drivers & Downloads to manually download and install Dell drivers. Learn more about updating drivers on your Dell.
Rolling Back Drivers
If you have audio issues after installing Windows Updates, try rolling back your audio driver to a previous version.
- In Device Manager, right-click the audio device.
- Select Properties > Driver tab and then select Roll Back Driver (if available).
If updating audio drivers or rolling back drivers doesn’t solve your problem, continue to the next step.
Step 5: Use Windows Audio Troubleshooter
Windows audio troubleshooter might be able to fix common audio problems automatically.
- Go to Start > Settings > System > Sound. Under Advanced, select Output devices and follow the on-screen prompts to diagnose speaker issues.
If running the troubleshooter doesn’t help, continue to the next step.
Step 6: Test External Audio Devices
If using headphones or external speakers:
- Check Connections: Make sure your headphones or speakers are properly connected or paired with your computer. Check the device’s user guide on Bluetooth pairing.
- Test on Another Device: Try them on another device to see if headphones or speakers work. If the audio device doesn’t work, contact the device manufacturer for support.
If the audio device works on another device, continue to the next step.
Step 7: Run Dell Sound Test
Dell laptops and desktops come with built-in diagnostics tools to check for hardware-related problems, including audio issues.
- Access Dell SupportAssist:
- Go to SupportAssist sound test. If SupportAssist isn’t installed, follow the instructions to install SupportAssist if needed.
- Review the Results:
- Once the diagnostic is complete, SupportAssist displays the results.
- If a hardware issue is detected, you may be guided to update drivers or contact Dell Technical Support for repairs or replacements.
- Use Dell Pre-Boot Diagnostics:
- If you can’t boot into Windows, restart your computer and press F12 several times during startup to access the One Time Boot Menu.
- Select Diagnostics and follow the prompts to run a full hardware check, including audio components.
