Cannot receive audio simultaneously on my pc and tv when streaming video from Netflix. To receive audio I must click on sound properties, playback, and either right click on my tv or my pc and click "use default". Only one will work at a time. I am using Windows 7 64 bit, processor is AMD Athlon 64 processor 3800+ 2.41 GHZ, 4 G of Ram, video is Nvidia Ge force gtx 465, sound is integrated Realtec AC97. Any solutions will be greatly appreciated.
