Unable to connect Bluetooth headset

Hello,

I have a new t490 with Bluetooth. I installed

bluez
bluez-utils
pulseaudio-bluetooth
(maybe others, I don't know what is relevant to this question)

Running

modinfo btusb

shows

filename:       /lib/modules/5.3.5-arch1-1-ARCH/kernel/drivers/bluetooth/btusb.ko.xz
license:        GPL
version:        0.8
description:    Generic Bluetooth USB driver ver 0.8
...

I am using the kde gui and when trying to pair it (to my bose) it displays

connection to the device failed

When examining the journal

journalctl | grep bluetooth

I see

a2dp-sink profile connect failed for MA:C_:AD:DR:ES:S_: Protocol not available

What could be the issue, and more importantly, the solution?

Re: Unable to connect Bluetooth headset

connect via terminal post error messages and journal logs verbatim without filtering use [ code ] tags consistently for all outputs.

I'm not sure what you want to see that I didn't write but here it is (in code tags)

bluetoothctl

[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent is already registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on

Re: Unable to connect Bluetooth headset

journal logs verbatim without filtering

grepping for bluetooth will lose you a lot of context. And it's unlikely that that single line was really all you got. FWIW there have been some reports with kernel issues so you might want to give the LTS kernel a shot.
