What does dolby pro logic and dts neo pc do on windows?

[chris_267]

I noticed the realtek audio driver can be unlocked and then you get dolby pro logic ii and dts neo pc. Are those features used to upmix stereo signals to 5.1? Do I need a receiver to use those features or can I just use my realtek 5.1 sound card?

Exactly what they are mate.
Pro logic generally for movies & neo is designed for music use.

A receiver ?? - no , just a powered 5 speaker set.

For standard usage an active 5.1 speakers set is enough.
I have a full home theater set + beamer connected to an htpc tho'.
