Bluetooth service "grayed out" and unresponsive

My dell laptop has had many issues with bluetooth in the past, including it dropping out or just refusing to turn on. It hasn't been able to connect to any devices for about a month (around when I upgraded to jammy jellyfish. I'm currently on kinetic and the issue still persists).

Running systemctl status bluetooth.service gives me the following error: bluetoothd[1000]:src/service.c:btd_service_connect() a2dp-sink profile connect failed for 88:D0:39:A2:C0:40: Protocol not available

Solutions I have tried to no avail:

Restarting the bt service from the terminal using sudo systemctl restart bluetooth
Reinstalling an older version of ar3k bt drivers
Installing pulseaudio-module-bluetooth

Any help would be greatly appreciated!!

This is NOT an answer but I have lots of data to provide for people eventually look into this and they do not fit in a comment.

I have a similar problem - Kinetic 22.10 fresh install, pipewire/wireplumber by default.

The BT earbuds w/ mic Jabra Elite 85t generally work good but sometime it gets messy after a while I have to put them back in the box, or even restart the system.

This is what happen on a freshly boot system when I get the Jabra out the box - and they automatically connect to BT as they're paired - from journalctl -f

Two potential issues here. First device is tagged as a keyboard...

(II) event24 - Jabra Elite 85t (AVRCP): is tagged by udev as: Keyboard

And the final line is red as in error:

bluetoothd[1129]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for 30:50:75:BE:B0:3D: Device or resource busy

If I run systemctl status bluetooth.service I get:

Suggest converting to a Community Wiki answer and ask others to add information. When it is (hopefully) resolved eventually, the relevant info can be edited into the question itself.

Definitely appreciate you adding the info here, but having it as a "Community Wiki" will be more palatable to some folks who might want to otherwise have it deleted.

Hi there, what exactly do you mean by converting to community wiki? I'm new to ask ubuntu and want this info to get out to as many people as possible so the bug can be fixed

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
