Hmm. I don't think I've ever run into that, and just tried it here and all seems okay.
All the control commands (play/pause/volume/skip, etc) act on the current zone.
I'm guessing that what's happening -- let me know if this is possible! -- is that HouseBand is controlling a different zone than you're listening to. So, it's pausing/resuming Zone 2, you're listening to Zone1, and so nothing seems to be happening.
You can ask, "What's my current Zone" to get information on that zone.
Unfortunately, there isn't a "Pause" / "Resume all" command. I'll look into whether there's a good way to add that in without recertification. Otherwise, I'll add it to the next "release."
Please let me know if it's a zone issue
