"However, it appears that you are still unable to resolve the issue. Here are a few additional suggestions that might help: > Make sure that your headphones are fully charged and turned on. > Remove the paired Bluetooth headphones from the device and then pair them again. > Try connecting the headphones to a different device to check if the issue persists. > Check if there are any pending updates for your Windows device. "
The headphones are fully charged and turned on. Removing the headphones and pairing again does not fix the issue. The headphones work fine with other devices. The computer and OS are up-to-date, as are the drivers for the headphones.
The manufacturer of the headphone says to ask Microsoft for help. The problem is clearly a Windows software issue - the headphones play a notification sound upon pairing, but will not play media, as they are not recognized as an output device.
This problem has not always been present. The headphones worked fine with computer for several months.
