Mac Mini--Dirac Live ---Beolab 5

The system: Audio all digital: Mac mini/Dirac live room correction--->TC impact win sound card--->beolab 5

TV/video-surround sound: Denon processor--->analog RCA into beolab 5and a pair or surround speakers.

As bl5's owners know, the speakers always prioritize digital sound over analog, so, in order to select analog I need to shut down the TC sound card. That's not to hard to do, but, when I go back to digital I wil have to: push the button the on TC Impact Twin, lower the volume (considerably, via beo4), turn on the TV where the Mac is connected to, grab the wireless trackpad, select Dirac Live program-because it looses connection to TC once turned off- restart it and woila' I'm finally listening to beolabs via digital.

I'm wondering if there is a way to make this process simpler. I'm willing to depart from the TC impact, but still, I'll have to shut down the mac because the bL5 still senses digital signal from it even if there is no sound going on.

So, my question is: is there a way or a b&o device that would allow me to force analog sound or force digital sound on demand without buying a TV?

Any thoughts?
