my setup is a win 7, 64bit computer with an on-board sound card plus a Terratec Aureon 5.1 PCI card. I use the on-board card for PC speakers (in the home-office) and the pci card is hooked up to the receiver (in the living room) via an optical cable. To be able to hear 5.1 sound via my receiver I have to use a special driver (http://code.google.com/p/cmediadrivers/), enabling SPDIF output on the pci card.
Now I would like to have my music played in the living room and the office simultaneously (using media monkey). Win 7 only allows for one output at a time per program. I tried the virtual audio cable to link the two outputs, but this does not seem to work with the driver I'm using for the pci card.
I am looking for a software solution, if possible. a good (external) sound card might be an option if it is within a reasonable price range.
