How to upmix stereo source to 5.1 on windows 10?

[chris_267]

Hello, I have a few questions. I recently bought a new desktop and logicteck analogue surround speakers. So I want to know how to upmix my stereo source to 5.1. I used speaker fill option from the realtek hd audio manager, but I am not satisfied with it. I'd prefer to use a Dolby pro logic II decoder, so then I tried installing Dolby home theater from my drivers folder that's in my C drive, but it says DHT cannot be installed. Why is it saying it cannot be installed? Does Dolby home theater have the dolby pro logic II feature? I download ffdshow. I know ffdshow has a dolby pro logic decoder in it, but how do I copnfigure the ffdshow audio decoder settings so I can upmix stereo to 5.1? Do I need a Dolby pro logic II receiver to use the Dolby pro logic II decoder in ffdshow? Do I need a different sound card?

why would you want to upmix? even if you upmix its not going to be the same. also speaker fill just pushes front channels to the rear.

get a cheap 5.1 usb soundcard or internal soundcard and output real 5.1. or, use optical with a soundcard capable of 5.1 over optical.

the problem is not with pc software.. if you are only outputting on a single 3.5mm no matter what you do it will be 2.0. you will need 3 connections for 5.1. the only thing pro logic would do is turn 2.0 files into sounding like they were 5.1.

Thanks for the reply. I want to create 5.1-channels from 2-channel stereo signals because I prefer upmixing and my realtek sound card already supports 5.1. For example, the front, center and surround speakers are connected to my on-board sound card through separate inputs. Isn't Speaker fill option similar to Dolby pro logic in the fact that it creates 5.1 channels from 2- channel signal? I assumed so, but it's not as good as Dolby pro logic II. Also, I don't want to use optical, because I don't have a receiver nor do I want one. I want my computer and sound card to do all the decoding and upmixing.

How should I configure the audio decoder in ffdshow so I can upmix stereo files to dolby pro logic II?

Is there a solution to fix the Dolby home theater error? Every time I go to install it, I get the error "DHT cannot be installed". Why can't I install it? Is there a solution to this problem? Do I need a different sound card? if so, which one?

Have you tried just plugging everything into your sub-woofer like your owner's manual states?
