First, the 990's second zone is an analog-only pre-amp, so no digital input will help. If you are just piping audio to the TV's speakers, I do wonder if garcianc2003 hasn't hit on a good idea - using the analog line output from the sound card to deliver audio to the TV. Then you can eliminate the Technics decoder and just use the 990 for surround duties. Sure, the sound card may not have as good a DAC as the Technics and almost certainly a step or three down from the 990, but in most cases the speakers in a TV won't be up to the task of showing the difference...
