I want to know if this is possible.

If you have a laptop, HDTV, and good 5.1 sound system, would you be able to use these to stream netflix videos?

I was thinking of course connect the laptop to the HDTV by a VGA cable.

However, I forgot about sound, all it has is a headphone jack.

I don't want to just output sound in 2.0.

The only way I could think of getting 5.1 sound out of this setup is to buy a USB soundcard for the laptop..... or is there a better way?

What I want to ask is.... would such a setup work to stream video in SD and HD from netflix on a HDTV with actual 5.1 sound?

If so, what usb soundcard would you recommend? I can't afford something too expensive (max $100, though even that is stretchign it for me, something around $50 or so would be ideal), and it would need optical out since it would need to connect to the receiever instead of directly to the speakers.
