Okay, so sound output is broken.

The Squeak tools are unlikely to help in this case. Sounds more like a VM 
problem - make sure the right sound module is selected (ALSA or OSS or Pulse). 
See the /usr/bin/etoys script and "squeak -help". The VM is just a C program 
that you debug pretty much like any other C program (even though parts of it 
are generated from Squeak code).

Also, if you compiled the VM yourself, pay attention to the configure output. 
If you do not have the right dev packages installed, some modules will be 
disabled and do not get built.

Also note there are various tickets regarding sound on d.l.o.
