I just remembered Turbo talking about a optical switcher a while back. Here is what he said:

I had a switch rigged to the usb soundcard(a turtle beach roadie)... when it was turned on, the sound was the pc, when off it would switch back to the ai-net input automatically... as soon as the light goes out on the fiber optic it switches back...
once in a great while it would not switch when the toslink went out, I then had to switch sources & it switches right away...
I have 5 different sources to select from, the pc is just one of them.... switching is easy & no problem....
Now the part I'm unclear about is if you have the optical PC source connected to the H701
AND have a Apline HU connected only with the analog (signal wise I believe) AI-net connector, would the HU still act as a master volume control for that other optical source?
