The Bluetooth headset is connected to the computer with an adapter

I first used the XP's built-in driver, and found that I could find headphones and connect to my phone, but there was no virtual sound card, so I couldn't hear the computer's voice. Then use the new version of IVT Bluesoil to install, all kinds of entanglements, and finally I can still find the headphones, but I can't pair them. After studying for a long time, I found that the output device in the sound options in the control panel has no Bluetooth option at all, so the system can only stream the sound to the sound card, of course, it can't be heard.

So I unloaded the new version of ivt bluesoil and installed the old version, the problem with the old version is that it has not yet obtained Microsoft's certification, so all kinds of prompts when installing, all the way to confirm (especially when installing the driver of the serial port, there will be about seven or eight times the same content prompts, and sometimes there will be 183 errors when installing, mainly because there is something occupied by the com port, or there is a software conflict). After installation, search for the device, select pairing after searching for the headphones, (there may be a lot of tangles in the middle, let's have a few more forms), refresh the service after pairing, and then connect the headphones, you can see that there is only one service: Bluetooth headset service, so that there is an outlet for sound streaming.

Then set the output device to Bluetooth Sco Audio in the sound options of the control panel, and you will find a rendering device for the sound stream. After that, press the headphone button a few times, and you should always be able to connect it once, and then you can listen to the song. Hey, it's complicated...
