I have a Sager W150ER with an Nvidia GT 650M. I recently did a reinstall of Win 7 (I was previously on Win 7) and now I can't get audio over HDMI. I have reinstalled the audio and video drivers a few times. In device manager the "high definition audio device" has an exclamation next to it, and has error code 10, which according to Google is a driver issue. Not sure what other info you might want, but ask and I can get it for you.
Thanks so much!
