Fixing Bluetooth Audio & Wireless Display in Windows

If you don't hear sound when using a wireless display, ensure the Bluetooth audio device is on, charged, and paired, and that the PC is playing audio through the right output. Ensure airplane mode isn't on, run the Bluetooth troubleshooter, update the Bluetooth drivers, and reinstall the Bluetooth adapter.

1. 
   1
   Make sure Bluetooth is enabled on your PC. If you're not hearing audio, or your Bluetooth speaker or other audio device isn't connecting, Bluetooth may be disabled.

   • First, if you're using a laptop, it may have a physical Bluetooth switch. Look for a key or switch with the Bluetooth logo
     
     , and make sure it's turned on.
   • Otherwise, open the Windows menu and click Settings (the gear icon).
   • Click Devices.
   • Click Bluetooth & other devices.
   • If the Bluetooth switch is off, click it to turn it on.
   • Disable airplane mode if turned on.
2. 2
   Make sure your Bluetooth audio device is on, charged, and paired. Whether you're having trouble with a Bluetooth speaker, headset, or headphones, ensure it's properly powered on and fully charged. If the device is on, turn it off, leave it off for a few seconds, then turn it back on.

   • If the device takes batteries, make sure the batteries aren't old–you can pop them into a different device to test them.
   • If the device is rechargeable, it may need to be recharged before it will work.
   • If you're having trouble pairing the audio device with your Windows 10 PC, this wikiHow Bluetooth pairing guide will help.
   • Also, make sure the device isn't too close to a USB 3.0 device that's plugged in to the computer–some USB devices can interfere with Bluetooth.

   Check the volume and audio output settings. If your Bluetooth audio device is paired but you don't hear any sound coming from it, the wrong audio output may be set. Here's what to do:

   • Right-click the volume icon in the system tray (near the clock).
   • You should see an audio device listed above the volume bar.
   • If the wrong audio device appears, select your Bluetooth device from the menu.
   • Ensure the volume is turned up and not muted.
4. 4
   Adjust the audio quality. If audio playback doesn't sound right when you're using your wireless display, you can adjust the audio quality manually. Here's how:

   • Right-click the volume icon in the system tray (near the clock).
   • Click Sounds.
   • Click the Playback tab.
   • Select your Bluetooth audio device.
   • Go to Properties > Advanced.
   • Select the highest quality available. The larger the numbers you see, the higher the quality.
   • Click Test to hear a preview.
   • Try with other quality levels if needed.
   • Click Apply and then OK.
5. 5
   Disable energy-saving features. If your Bluetooth audio keeps dropping out and you're using a laptop, your computer may be in a lower power mode. Here are a few features to check:

   • Battery saver mode
     • Click the speech bubble icon in the system tray (near the clock).
     • If Battery Saver is enabled, click to turn it off.
   • Bluetooth energy saver
     • Right-click the Windows Start menu and select Device Manager.
     • Expand the "Bluetooth" menu.
     • Right-click your Bluetooth adapter and select Properties.
     • Click the Power Management tab.
     • Uncheck the boxes and click OK.
6. 6
   Run the Bluetooth troubleshooter. Here's how:

   • Open the Windows Start menu and select Settings (the gear icon).
   • Click Update & Security.
   • Click Troubleshoot.
   • Select Bluetooth under "Find and fix other problems."
   • Click Run the troubleshooter.
   • Follow the on-screen instructions to fix any issues identified by the troubleshooter.
7. 7
   Restart the Bluetooth service. Here's how:

   • Press the Windows key, type services.msc, and press Enter.
   • Click the Name heading to sort the services in alphabetical order.
   • Right-click Bluetooth Support Service.
   • Select Restart.
8. 8
   Update the Bluetooth drivers. If Bluetooth problems persist after using the troubleshooter, the problem could be related to your Bluetooth drivers. You can try checking for an update in Device Manager:

   • Right-click the Windows Start menu and select Device Manager.
   • Expand the "Bluetooth" menu.
   • Select the name of your Bluetooth adapter (which may include the word "radio").
   • Right-click the adapter and select Update driver.
   • Click Search automatically for updated driver software.
   • Follow the on-screen instructions to update.
9. 9
   Uninstall the Bluetooth adapter in Device Manager. If no new driver was found, try uninstalling the current adapter, which will force Windows to reinstall a fresh version of the driver:

   • Right-click the Windows Start menu and select Device Manager.
   • Expand the "Bluetooth" menu.
   • Right-click your Bluetooth adapter and select Uninstall device.
   • Shut down your computer.
   • After a few minutes, turn your computer back on.
   • Try pairing your Bluetooth audio device again.
     • If pairing doesn't work, go back to Device Manager, click the Action menu, then select Scan for hardware changes.
10. 10
    Make sure your Bluetooth audio device is compatible. For the best results from a Bluetooth audio device, the device will need to support the A2DP protocol. To find out if yours does, you can check the documentation that came with the device, or search the web for the device name and "a2dp."

Fixing Wireless Display Issues

1. 
   1
   Restart your PC and the wireless display. No matter the issue you're running into, a quick reboot of your computer, as well as the wireless monitor, TV, or projector you're connecting to, will often fix the problem.
2. 2
   Make sure Wi-Fi is turned on. Even if you're connected to the internet via Ethernet, you'll need to enable Wi-Fi on your Windows 10 PC to use a wireless display or mirror to a TV wirelessly. You can check by clicking the network icon in the system tray (by the clock)--if the Wi-Fi tile is turned off, click to turn it on.
3. 3
   Disconnect and reconnect to the wireless display. If you were able to connect to the display but are having trouble with video playback, try this:

   • Open the Windows Start menu and select Settings.
   • Click Devices.
   • Click Bluetooth & other devices.
   • Select your wireless display.
   • Click Remove device.
   • Reconnect to the wireless display.
4. 4
   Check the input on your wireless display. If your wireless display is a TV or another display device that supports multiple inputs at once, you may need to use the buttons on the display or the remote control to switch the input. This is a common fix if your computer says you're connected to the wireless display but you can't see video on the device.

   • On most remotes, and on the back of most displays, you'll press a button that says "Source" or "Input" to change the input. Keep pressing it until you've gone through all the inputs.
5. 5
   Temporarily disable your firewall and other security software. If your network firewall is blocking certain ports or protocols, you will run into problems trying to project to a wireless display. Disable the firewall to see if that fixes the problem. If you're trying to connect to the display at work or school, you'll need to contact the IT helpdesk to ask if there are any firewall rules in place that would block you from using Miracast to connect your Windows 10 PC to a wireless display.
6. 
   6
   Make sure your devices support Miracast. If you are having trouble connecting to a wireless display, either the display or your Windows 10 PC might not support Miracast. Here's how to check:

   • On your PC, press the Windows key on your keyboard, type connect, and click Connect in the search results.
   • If your device supports Miracast, you will see it here.
   • For the display you're connecting to, check the documentation to see if it supports Miracast. If you don't have it, you can search the web for the specific model number (check the back of the display) and "Miracast."
   • If the display doesn't support Miracast, you can add Miracast capabilities by connecting a Miracast adapter to its HDMI port.

Tips

• If your wireless display doesn't support Miracast but your PC does, you can project your PC's screen to another PC that's using a Miracast display. To do this, log in to the other PC, go to Settings > System > Projecting to this PC, choose Add a feature, and enter "wireless display." Select Wireless Display and click Install. Then, you can select this PC as a wireless display from the original PC.

• Another option if your wireless display doesn't support Miracast is to connect to a TV. Most TVs do support Miracast, so you should have no trouble mirroring or extending your Windows 10 PC's screen to your TV.
