I solved the issue formatting and reinstalling windows from scratch, any other solutions failed.
Hi everyone, I am using my Sony xm2 Bluetooth headset over my XPS and my docking stations for a couple of years, all working well until a couple of weeks ago. I am now running W11 for a while but after a few updates (Windows and drivers from Dell SupportAssist) if I have my headset connected and I start an MS Teams of Zoom call, the app freeze, and the audio system crash, it doesn't allow me even to use another device. I need to troubleshoot the service to let it start again and it works only with wired audio devices. Few additional info: Any suggestions?   thanks and have a wonderful day, Simone
