[Vm-dev] Audio problems on Linux - part 2 (PulseAudio)

[Phil B]

I was going through the github issue log to report the issue from part 1
and found this: https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/360.
This is this issue and the workaround.

If I use LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libpulse-simple.so.0.1.1 to
force load the missing library (it is also accessible via a
symlink /usr/lib/x86_64-linux-gnu/libpulse-simple.so.0) then the PulseAudio
driver loads and recording works perfectly for me on Debian.  So the OSS
driver still has issues and the PulseAudio driver isn't linked properly
(for Debian 10 at least) but can be made to work.
