This question already has an answer here:

I would like to upmix 2 channel audio sources such that they use all of my 5.1 speakers. I have a realtek sound card (with updated drivers) and Windows 7.

Here's what i've tried:

  1. Using the "Speaker Fill" option under the speaker properties "Enhancements" tab. This tries to guess what the audio should sound like in a 5.1 environment which results in only parts of the audio being played out of the additional speakers. I could deal with that if it were only the rear speakers but it also impacts the sub too. The 2 channel audio sources have significantly less low-end than true 5.1 sources when using "Speaker Fill".

  1. Using the "Room" environment. This seems to help a bit but it also introduces a slight echo effect/distortion that can be annoying with certain music/sources.

I'm MusicBee for playing music as it has it's own upmix option that works perfectly. The rear speakers are exact clones of the front speakers and the subwoofer sounds great too. I'd love to be able to have that same quality upmix with other sources such as YouTube.

Are there any other options out there?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Windows 7 does not natively support this, but my Creative Soundcard has this option and I would not be surprised if your realtek card has it too. Can you edit your post and give a full list of options you have? I can then look if such option is present in your case. You might have to use speaker fill in conjucntion with loudness equalization, but there also might be another option. – LPChip May 24 '15 at 21:26
  • @LPChip. Loudness equalization doesn't seem to help. The only other option that makes any sense is Bass Management but that isn't helpful either. I suspect that they solution may come in the form of a "virtual sound card". I tried some software called "Virtual Audio Cable" but as far as I doesn't do exactly what I want. Which sound card do you have? – diolemo May 25 '15 at 16:42
  • Creative X-Fi Elite Pro, but any X-Fi will have it. I also have the Creative X-Fi 5.1 (USB) one which is very limited, and I was still able to get it to work in there (but it was harder) – LPChip May 25 '15 at 16:54
