Bug#1120277: linux: I'm filing this because I have a serious, persistent bug with my Intel AX210 Bluetooth audio on Debian. The problem isn't configuration; it's a kernel driver failure. My Bluetooth headset connects, but I get absolutely no sound.

Did this work for you with *any* earlier kernel version?

Can you test with Wireplumber instead of PulseAudio?  I ask because that
is now the default audio mixer on Debian, and it has worked for me with
the similar AX200 Bluetooth adapter and various Bluetooth audio devices.

What happens if you run:

    pactl set-default-sink bluez_sink.F4_9D_8A_88_50_6F.a2dp_sink

?
