Boy, your mental toolbox is chock full of costly, expensive and ineffective solutions, isn't it? ;-)
One word: transformers.
The switch isn't anythng to do with a ground loop---
Really? It may or it may not, depending on a lot of details that haven't been explored.
and if you look earlier in the thread - 'you brought up the ground loop isolator' - I just mentioned I happened to have a 'ground loop' problem, and now we are on a different subject.
Not at all. You brought up ground loops. The Ground Loop Isolator which is a pair of high quality audio transformers, is about as close to a one-size-fits-all solution to ground loops and other sources of hum as is known to man.
The switch is to keep two different items from clashing one another:
How the switch intersects with grounding relates to hum.
Currently I have a DVD player with 6 discrete outputs that goes out to my older 5.1 audio receiver with no decoder - My audio receiver has no switch for its 5.1 inputs. So I want to build my own via - wiring these items together with Y-Adapters.... I don't use the DVD player that often but when I do I would turn off the Computer source at the Cat6 cable switch that I'm planning I'm building. -- -The circuit would go from 2Cat6 to 6discrete RCA.
The simple answer is that if your AVR has digital inputs and the DVD player has digital outputs, then go that way. That leaves the 5.1 input free for other purposes, right?
It's hard to provide a solution for a system that is only described in fragments.
Transformers??? explain - sounds expensive... Aren't those the things that get knocked out when lightning strikes them.
edit: "more than meets the eye"...lol
The Ground Loop Isolator that you say you already have is basically composed of two transformers.
