[QUOTE="user 997, post: 620600, member: 997"] Unless it's bit perfect playback in both implementations, I'd expect to see or hear differences between the two. Also good chance that your Nvidia card has HW acceleration, while it might be a software (e.g. driver) implementation on the Intel, though today I think all GFX cards have some form of HW built-in acceleration. Then it can be a function of how the driver level software reads and processes that data. There is also a good chance if it goes through the Windows audio environment that it might apply EQ, resampling and other sorts of nasties before outputting it on HDMI. What you are hearing sounds typically like the Windows audio volume mixer in action. [/QUOTE]
