Ok so I have Realtek sound on the motherboard and also nVidia audio courtesy of the GTX660Ti. My TV is connected to the graphics card through HDMI but I want to use the onboard sound and not the NVidia audio. I have no other audio connections or equipment, just my TV. I get the Realtek sound when connected to the HDMI on the motherboard but this is obviously no good. How do I do this? Using the NVidia sound renders my front panel useless.
