Desktop computers generally do not have Bluetooth function. After purchasing Bluetooth adapter, they can connect with Bluetooth speaker. Driver installation is successful. Audio also indicates that the connection is successful. A2DP connection is always unsuccessful. Player device can not be modified to Bluetooth playback. It can only be modified to the top of hands-free, but there is no voice at all. Xiaobian tells you the answer.
1. First, check the driver according to the online tutorials
2. If the driver has no problem, then turn on the playback device to see if both bluetools are normal. If only Audio is normal and Renderer is dark, then it is the problem of Bluetooth settings.
3. Turn on Bluetooth on your computer to see if A2DP can be connected. If the connection is unsuccessful, turn on Bluetooth settings.
4. Turn on the Bluetooth audio/video settings, remove the following ticks that only connect to the front of the headset that has started content protection, then connect to the A2DP, modify the playback device and switch to the Bluetooth Audio Renderer, so that you can use the Bluetooth speaker.
