Had power failure here over the weekend - this particular system has issues with USB audio device ordering on reboot (it's on a UPS but the power outage was longer than the battery life). So I've decided it's time to upgrade that system, sooner than I had planned to do it. So it will be on and offline for the next 48 hours - for the past day or so the audio devices have been ordered in correctly. Better to have them offline than broadcasting the wrong channels.
