Hmm, updating a Pi can be confusing at times.

If you do 
`uname -a` in a terminal, what do you see?

On my still-alsa machine I get
Linux Goldskin 5.4.51-v7l+ #1333 SMP Mon Aug 10 16:51:40 BST 2020 armv7l GNU/Linux

On my test-pulse I get
Linux Pi-4-1-pulse 5.4.79-v7l+ #1373 SMP Mon Nov 23 13:27:40 GMT 2020 armv7l GNU/Linux

Remember that you need to include the vm sound flag when you start up squeak! I keep forgetting that. Though.. if you're start scratch with the standard menu entry, that should do it. Let's see - there is also the possibility you are not directing sound to the right output. The Pi sound-volume control widget on the menubar can set where the sound goes - right-click on it and you should see a menu with at least
  Analogue
  HDMI
entries. I use the analogue and headphones since none of my Pi have a direct HDMI display attached but go via VNC. If you have an HDMI monitor attached it may not have speakers or you might not have them turned on! DAMHIKT.

The 5.3 armlinux package from squeak.org ought to do ok for this. Remembering of course to include that '-vm-sound-alsa' (or pulse) in your commandline
