[SOLVED]Bluetooth earbuds connected but no sound

I'm setting up a new laptop with pipewire, and the pipewire, pipewire-pulse, and wireplumber daemons are all running. With bluetoothctl, I have successfully paired and connected my bluetooth earbuds. But still I'm not getting any sound out of them. (There is sound in the speakers, and the physical audio jack with wired headphones, and the earbuds work with other devices.)

What am I missing?

This is what I see with pactl list cards and pactl list sinks, but I'm not sure how to interpret this:

pactl list cards:

Re: [SOLVED]Bluetooth earbuds connected but no sound

In the list of cards I don't see a Bluetooth device. What is the output of 

systemctl status bluetooth

?

I should have mentioned, bluetooth is running and my bluetooth mouse works fine:

Also, the earbuds are connected with bluetooth, but they just don't make any sound. Even when they're paired and connected, the sound comes out of the speakers. The earbuds work fine when connected via bluetooth to my phone.

Re: [SOLVED]Bluetooth earbuds connected but no sound

This does not show that the Bluetooth device is connected. It shows that your Bluetooth card is scanning and getting a response from the earbuds. To pair you need to run the following commands while inside the bluetoothctl shell:

pair F4:0E:11:74:86:B0

And then to connect:

connect F4:0E:11:74:86:B0

Re: [SOLVED]Bluetooth earbuds connected but no sound

The device was already paired, but not connected. But even after connecting, I still wasn't getting any sound until I realized that the reason had nothing to do with Bluetooth, but the active Pipewire output. In pwvucontrol once I changed the output device from headphones to the now-visible Bluetooth earbuds, sound started working. Thanks!
