[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] Problem linking Linux Sound Library (#360)

[karl ramberg]

Sound on Linux seem to be a mess.
I'm on Ubuntu 18.04 and had no sound from Squeak.
I got this error in the terminal: dev/dsp: No such file or directory
I installed package osspd and that seem to solve the problem.
(sudo apt-get install osspd)

Best,
Karl
