Not accurate, in my experience.  I've had numerous problems with the VM and
Pulse over the years (reported at least a couple of times here on the list,
never resolved for any length of time) and so I've fallen back to using
padsp to reliably get audio support for Squeak.  I'm currently running
Debian 10 and it has been a combination of various VM builds (needed to fix
issues) not including Pulse Audio support to sometimes the build includes
it but it just doesn't work.
