Hello everyone, I just bought a new PC, here are the specs: Case: Fractal Design Pop XL Air RGB Power supply: Corsair RM850X 850 watts (80+ gold) Motherboard: ASUS TUF Gaming B650-Plus Wi-Fi, AMD B650 Processor: AMD Ryzen 7 7800X3D 8x 5 GHz RAM: 32 GB DDR5 PC-5200 RAM (2x 16 GB) Graphics card: AMD Radeon RX 7800 XT 16 GB, any manufacturer SSD M.2: SSD NVME M.2 2 TB Kingston NV2 Wireless LAN: integrated WiFi 6 wireless LAN + Bluetooth module CPU cooler: Be Quiet! Dark Rock 4 Operating system: Windows 11 Professional 64-bit But it's impossible to connect any Bluetooth device (including my Sony XM4 headset, which I'm interested in, but also other BT sound devices). I've followed all the tutorials available on the Internet (check the BT drivers via Task Manager, search for the headset manually via BT settings, update Windows...). I'm starting to go round in circles and I can't figure it out anymore... Any ideas? Thanks a lot!
