Comment 3 for bug 1578217

I'm still experimenting but some early observations:

 - pulseaudio on classic is a very simple interface that adds very little permissions and doesn't need any changes to ubuntu-core-launcher
 - a full blown pulseaudio snap needs research
 - shm_open(), in general, is still not solved due to POSIX design
 - more research is needed

I'm now looking at additional applications (chromium, dosbox)
