always-on setup (has auto-switch functionality changed?)

[meeotch]

btw - this may sound like a minor issue to most people, particularly anyone who uses Spark consistently.  But in my case, it pretty much prevents me from using my Phantoms.  As I explained to Julien:

My only audio source is a PC, which runs my home automation system. So I use it as an alarm clock, as a security measure to play music at preprogrammed times when I'm on vacation, to play music via voice command, when someone is at my door, etc.  I'm now unable to do any of these things while using the Devialet system as an output.

If anyone has a clever idea for a workaround, please post it.  I'm thinking maybe I can program my computer to emit a very low level audio "ping" every few minutes.  Low enough not to be audible, but loud enough to keep Auto-Switch "awake".
