That's not exactly the problem. 
The hang is intermittent. Run often but fails only sometimes, and always on an OL VM
I'm looking at logs where a particular VM exhibited the hang 2 days ago but not long before that the test passed in a different run on that same VM in just 35 seconds, no problems.
A hang one in 100 times doesn't sound like much until you know that it can get run 20 times a day .. so every few days you have a failure. Those numbers aren't exact but are in the ball park.

I also think it doesn't help that without the sound keyword the test can be run concurrently with other (sound) tests.
Which means there's perhaps others that might theoretically need the keyword too.
