This concerns Windows 11 24H2 on my new TUF Gaming B650EM-E WiFi motherboard. I have an Intel AX200 PCIe card I normally use for Bluetooth, but I decided to try the builtin Wifi/Bluetooth, which is a MediaTek MT7902. I don't use Wifi on this PC, so I installed only the Bluetooth driver, and while it works, it takes 20 seconds to go from the Connected state to Connected Audio. This happens with my Bose QC Ultra earbuds and AirPods Max headphones. I tried both the drivers on Asus's web site and the more recent ones linked in MoKiChU's thread. In contrast, my AX200 makes the audio connection almost instantly, as did a USB adapter I used a few years ago. I've never seen anything like the MediaTek poor performance. Is this typical? I've gone back to the Intel, but I might try the builtin again if I get some ideas on fixing the problem.
