Audio problems on Linux - part 2 (PulseAudio)

Phil B
 
I'm not able to get the PulseAudio driver working on Debian 10.  When I try squeak -vm-sound-pulse I get:
dlopen: /tmp/sqcogspur64linuxht-20190724/lib/squeak/5.0-201907242041/vm-sound-pulse.so: undefined symbol: pa_simple_write
could not find module vm-sound-pulse
Aborted

When I run squeak --help I get the following listed as available drivers:
  vm-sound-null
  vm-sound-OSS
  vm-sound-NAS
  vm-display-null
  vm-display-fbdev
  vm-display-X11

Finally I do an ls of the vm library directory and see the .a and .so files for vm-sound-ALSA, vm-sound-NAS, vm-sound-null, vm-sound-OSS, and vm-sound-pulse.

Assuming the PulseAudio driver should be working, I'm not clear on whether this is a VM build issue, a missing package on my system, or some other unresolved issue on Debian.  Suggestions appreciated...

What's the output of this:
`ldd /tmp/sqcogspur64linuxht-20190724/lib/squeak/5.0-201907242041/vm-sound-pulse.so`

And are you sure, pulseaudio is installed on your system?

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.
