Interested in adding the wiim pro to my av receiver setup but I had a question. The hope is that I can put the wiim pro inline between my TV and AV receiver using optical in/out on the wiim pro. I am interesting in it being inline, so I do not have to change the input on my receiver. I would depend on the auto sensing feature, where if its not streaming music and it detects sound on optical it will pass that audio through. The challenge here is, I have a 5.1 surround sound setup with my receiver and do not want to loose that surround from TV -> wiim -> av receiver. Would it pass the 5.1 signal to the AV receiver? Now I assume it will pass a stereo signal when its streaming music to the receiver.
