I have 2 computers and want to connect them to my Pro 4.1's. I tried using simple Y adaptors but the sound cards signal compete with each other degrading the sound quality. I have seen posts on this subject and people have mentioned some sort of op-amp mixer switch that would work. Can someone please elobrate on this type of switch with details on who makes and where I can buy one or if some other type of adaptor would work. Someone mentioned labtec made a switch. I checked out their website and could not find one. Any help would be appreciated.
