Ubuntu 21.10: Bluetooth headphones pair but PulseAudio doesn't discover it

cn flag

I'm running ubuntu 21.04 on a framework laptop with an Intel Wi-Fi 6E AX210 wireless card. I downloaded the iwlwifi-ty-59.601f3a66.0.tgz driver from here and put it in /lib/firmware, so should be up-to-date. Also all my packages are up-to-date.

I want to listen to audio through my bluetooth headset instead of the laptop's built-in speakers. However, it doesn't seem to show up in pavucontrol no matter what I do, despite the headset successfully pairing. More details below.

My bluetooth device is successfully pairing:

$ bt-device -i 00:0E:DD:71:B0:6B

However, I can't get it to show up in pavucontrol:

$ pacmd list-sinks
1 sink(s) available.
  * index: 0
    name: <alsa_output.pci-0000_00_1f.3.analog-stereo>

I have the module-bluetooth-discover and have tried:

$ pactl unload-module module-bluetooth-discover
$ pactl load-module module-bluetooth-discover
25

Here's the output of list-modules:

$ pacmd list-modules | grep -i bluetooth -B 1 -A 5

        module.version = "15.0"

Here's what I find in dmesg:

Any ideas on how to proceed from here?

Is it a bluetooth card in the machine or a USB device?

The Intel Wi-Fi 6E AX210 should support bluetooth, I believe

Did you do a complete shutdown and then boot? Does this computer have another OS?

Yes to the first question, no it just boots Ubuntu 21.10

Did you ever end up figuring this out? I'm still trying to get the mic on my Shure TW2 working under Ubuntu, but no luck...

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.
