Hi Eddie Buffum
Welcome to the Microsoft Community
Understanding your problem, the user's Sony WF-C510 Bluetooth headset can be connected to the computer, but does not show up as an audio device
To set as default playback device
- Go to Control Panel -> Hardware and Sound -> Sound.
- In the Playback tab, right-click on the blank area and make sure Show Disabled Devices and Show Disconnected Devices are checked.
- Find your Bluetooth headset. If you find them, right-click and select Set as default device.
Install or update the drivers for your headset
- In Device Manager, locate and right-click the device, then select Update Driver.
- Select Automatically search for updated drivers to let Windows help you automatically search for and install the most suitable drivers.
Ensure the correct Bluetooth profile (A2DP)
Confirm that the headset is using the A2DP profile:
- Locate your Bluetooth headset in Device Manager, right-click and select Properties.
- Go to the Services tab and make sure audio sink, handsfree telephony, etc. are enabled.
Reset the Bluetooth adapter
This can sometimes be caused by problems with the Bluetooth adapter itself and can be resolved by trying the following steps:
- In Device Manager, locate your Bluetooth adapter, right-click and select Uninstall Device.
- Disconnect the Bluetooth adapter (if standalone) and reconnect it, or restart your computer to allow the operating system to automatically recognize and install the adapter driver. If it does not install automatically, please go to the corresponding manufacturer's support page to download it manually.
Try a different USB port (if using an external Bluetooth adapter)
If you are using an external Bluetooth adapter, try plugging it into a different USB port, especially the rear USB ports, which are usually more stable.
Make sure the operating system is up-to-date
Sometimes there are bugs in the operating system that can affect the normal use of Bluetooth devices. Make sure your Windows system is updated to the latest version:
- Open Settings (Win+I) -> Update and Security -> Windows Update.
- Click Check for updates and install all available updates.
Bluetooth headset reset
If the above steps do not work, try to reset your Bluetooth headset:
- Refer to the Sony WF-C510 user manual or the manufacturer's support website and follow the instructions to reset the headset.
