Unfortunately I replicated those same failures. All five speakers work just fine in Windows (using qemu) although the played back verbs will only continue activating the same speakers. When I tested it I was able to "break" and "restore" the speakers using different verb-sets, so while it's definitely making some changes, it doesn't seem to be impacting the bottom speakers in the slightest.
