How do I Connect a Sony Bravia HDTV (KDL-32BX300) to an HP Touchsmart 9100, using an HDMI and DVI cable, and an audio cable to play things from the computer on the tv. I can get a picture but no sound on the tv. I think I have tried every combination but am not sure. The manuals are no help. I *have* gotten tv sound on the PC. But I want PC sound on the TV. Any guidance? Thanks!
