I've played around some more and updated the report.

AFAICT the failure comes from the combo of the missing pulseaudio plugin and the #stopSoundWhenDone preference.

The vm2022 has the plugin but vm2196 didn't.
RC5 has the preference set.
So RC5 with vm2022 works ok. Sound works the preference stops the latchup after a while. 

RC5 (or any other recent image w/ the preference) and vm2196 (plugin missing) Sound works but after the latchup has stopped the next ctrl-d will cause the image to quit.

This may not be the true cause of the problem but I am pretty confident it would explain all the phenomena.

Yours in curiosity and service, --Jerome Peace
