How to properly set up bluetooth headphones ubuntu 20.04?

Question

linux

Hello.
I recently updated a bunch of packages in the system (standard update) and my bluetooth headphones stopped connecting.
reinstalled pulseaudio, pulseaudio-module-bluetooth, bluetooth, bluez, bluez-tools, rfkill. In general, everything that I found in articles on the internet. Headphones are now connected and playback control works from them, however, the sound output does not change to headphones and they, in principle, do not appear as a sound output source.
How to reconfigure this system to work correctly?
Thank you in advance.

pulseaudio-module-bluetooth

there is a problem in it if they are not in the output devices. But it is treated with shamanism. Right now they are sawing pipewire instead of pulseaudio, maybe there sound via bluetooth will work more predictably and reliably.
