    Yeah, it helped. Now my laptop can see bluetooth devices, but my bluetooth headset doesn't play any sounds.

    That looks correct, check the sound settings and see if the speakers are listed as an output device using A2DP

    If I could have figured out what in in that kernel that I didn't add to the 5.19 source code. Can you post results for
    Code:
    sudo dmesg | egrep -i 'blue|firm'; sudo cat /sys/kernel/debug/usb/devices | awk '/3571/' RS=
