I've just got a new computer, and I can not get the sound to work in Windows Media Center when I'm streaming Netflix. The sound works fine when I stream Netflix through Internet Explorer, and all other media formats have no problem with sound in Media Center, i.e. DVD, Blu-ray, Broadcast TV.
I tried updating the audio card driver, and that didn't help. I did get the sound to work if I hook the monitor up through the HDMI port, but the sound goes to the monitor and the speakers are quite horrible...and when I hooked the speaker back up to the green 1/8" jack, the sound when away. So, I tried just hooking up the monitor with a VGA instead so the sound would not be ported through the HDMI output, but that still did not work. It's got to be something simple.
Like I said, sound works on everything except Netflix in Media Center. I'm running Windows 7 64-bit.
