It would seem extremely unlikely that you'd need to manually install more PulseAudio packages. The general rule with installing packages is that if you don't know why you need it, don't do it. This rule is even more important when you're trying to install packages for completely separate subsystems (installing audio packages to fix Bluetooth, for example).
However, updating your packages is pretty easy, and should be done regularly. Just pop open a terminal and run these two commands:
sudo apt update
sudo apt full-upgrade
This will upgrade all of your packages and programs to the latest versions known in the Ubuntu repositories and any additional PPAs that you may have manually added to your system.
