And you want to output audio from your PC to your tv? Does your tv allow audio in via optical, or audio out? If audio in, then you should be able to just get an optical toslink cable to connect from pc to tv. but that's not going to give you video. either you need a pc card that does HDMI out and a tv that supports it, or a card that does component video out, or vga or dvi out, and a tv that supports component video, vga, dvi in (or s-video, though that's junky).
