Dolby Home Theater in my laptop?

I have an old lenovo y510 with me. Well it has got Dolby home theater option in realtek driver setting. How do you rate this?

The setting : http://i46.tinypic.com/256d5sl.jpg

Is this a hardware processing or s/w procesing?

Also i have heard loudness equalization (microsoft) setting ruins the experience whats your opinion on that?

Now i see dolby home theater v4 ads all around the web.. whats my version is there any relation to this?

Do you recommend turning this realtek setting on...as shown in the pic?

 

If you're asking about the simulated 5.1, then it simulated via software manipulation. The quality of the hardware, however, plays a role in the aural experience as well.

Loudness equalization/volume leveling almost always is a hindrance. You get better quality out of manually adjusting your volume, rather than have the db level something was recorded in manipulated.

I'm not sure what version you have, but you should find an "About", or you can click on that (i) in the bottom right corner.

As for using the software (or that 5.1 feature, specifically), it's a per user preference, really. I've never had any gripes, although the simulation is far from an adequate replacement for a true 5.1 system. You can get excellent headphones with more than 2 speakers/channels that really help with the experience in simulation.

 

This is something I was also wondering, it has a stock Realtek HD but even the default Music setting on Dolby Profile it makes quite a difference. Is there anything in the hardware thats a little bit different to whats in the vast majority of systems?
