Sound quality from PC's VGA HDMI output to 5.1 home theater receiver?

[daylight]

Can somebody explain me how the sound is transfered to VGA card HDMI output? Will I feel the difference in quality if I use onboard soundcard or dedicated PCI soundcard to output audio via VGA card's HDMI?

Hi, I have the ATI 3870 Graphics card hooked up to my amp via HMDI.
The graphics card has a sound chip built in. So no seperate souncard is needed.
I have it connected this way as it's just convienent to send both audio and video down one cable.

I think this audio chip on your VGA is just for audio pass-through from your real soundcard. Or am I wrong?

Hi Daylight,

You're wrong on this occasion. ATi cards do actually have on board sound chips (from Realtek) which shows up as a distinct device in "Device Manager", needs its own driver and is configured separately from any other sound device.

The NVIDIA method is to use SPDIF pass-through from an existing soundcard (unless you have an nForce MoBo with integrated HDMI that is).

Hope this helps.
