After update BlueTooth earphones successfully connects but no sound

I used bluetooth audio (bluetooth earphone) often, but after update it successfully connect and recognized but no sound. Have tried restarting pc as well.
Normally it works but sometimes I have to systemctl restart bluetooth otherwise it will be unable to connect.
The earphone is not broken, it still worked on my phone.

Actually I’m not sure if it’s this update or previous one but it should not be too far.

As I wrote this post, I have not attempted to fix this issue.

EHH… sorry. It worked just now.
I don’t understand.

Earlier after multiple restart and replugging, the bluetooth is not recognized in Output Device.
Now it’s there right after I wrote this post. Magical.

However unlike in the past, I had to manually change it now.
Well, I guess bluetooth audio will always be mysterious for me.
