I have a laptop Lenovo y9000p 2022. On the laptop, I can connect the Bluetooth devices, but the laptop cant stable output sound through the Bluetooth devices.
I have tried to clone the git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git, and replaced the intel folder, and reboot the laptop, and still not work.
