  • Stereo audio through all 5.1 speakers

    hi there,

    i have searched and searched all across this forum and google and i just can't find the answer i am looking for so here goes:

    i have 5.1 surround sound in the car, i want this to work as a true 5.1 for all the things that support it like DVDs etc,

    but anything that isn't 5.1 like regular stereo audio, even the windows sounds etc, basically every other noise the computer makes, i want "upmixed" so that it comes out of all the speakers too.

    now in my searching i have come across lots of programs and plugins that will do this in things like WINAMP etc, and i have VLC media player which does this fine, it plays stereo sound through all the speakers automatically which is great.

    but i want something that does this for all sound. an example is youtube videos are only played through the front speakers.

    i am using a RealTek ALC888 chip, with the latest realtek driver, for windows XP. it doesn't support "upmixing" or "speaker fill" (which is the terms i have found in my searching)

    i could of course wire it physically, but then i would loose the real 5.1 surround sound on the DVDs.

    is there any kind of modified driver, or background program that can auto upmix any stereo audio, but keep the 5.1 if its available?

    thanks everyone

    Have you tried Virtual Surround?

      If your onboard audio doesn't support virtual surround, you might want to try using a USB sound card that's bundled with software that does all of the audio manipulation you need.

        thanks for the replies guys, can you tell me a little bit more about Virtual Surround? is it an option in the driver? because i have been all over the Realtek driver and i don't think it has any kind of option. the closest i got was setting the "effect" to "room" which gave me the upmixing but also added this distorted reverb which ruined the sound.

        as for another audio, or usb sound card, i would really like to avoid that, mainly because i don't want to use up too many genuine usb ports, and i want to make use of all the internal parts if possible, i have modified the motherboard to use its internal microphone amp to amp the centre speaker so i dont need an extra external amp for one speaker, and that works pretty well, so if i could use the existing setup that would be great. also i am very pushed for space, every extra box adds a big problem.

          I don't think there's much you can do with the Realtek driver. I have it on my mini-itx board and it's really basic.

            yea its really disapointing, but its such a common chip and actually the sound quality is great, i was wondering if anyone had modified it? or something like that. or it it is possible to have a program working with it that can give me the surround sound.

            i had a look into virtual surround sound, and i don't think it is what i am after. it would take my front speakers and try and create a surround sound effect using just those two speakers. but what i want is when ever my computer plays audio out of just the front speakers i just want it to copy it to the back, so the people in the back of the car get the sound too.

              i can think of a overly-complex way of doing this using audiomulch... you save 2 setups-- one is the stereo setup-- and distributes everything to all channels, and the other is your surround setup-- which each input goes to each output..

              the problem is that you need to manually launch each one, and that AM is $180...

                hmm, well i wanted things to be automatic, because i could probably rig some kind of bilateral switch to join the front and rear speakers together by pushing a button, but i don't want to have to do that for something that seems so simple

                  Hmmmm, I thought people went with a USB sound card to unload some of the burden of the CPU anyways...

                  Anyways, this is what I have:

                  http://www.newegg.com/Product/Produc...-101-_-Product

                  It's only $21, and it comes with a program that enables virtual surround. Plus there's other options in there too, but I haven't dug around too much yet.

                  I'm sure there are plenty of other options out there other than this one.

                    +1. That's what I was using before I switched to a DAC. Plus, you can increase/decrease the db for each speaker in case it's too soft/loud.

                      thanks for the info, that looks like a useful usb adapter.

                      but again, i have all the equipment in the car, everything is perfect except for this,

                      i am not worried about CPU burden, and its more important that i have the extra usb port. i have been looking at upmixers, but they are all for rendering programs for people who are converting video etc,

                      so still square one. there is one hope, people seem to be hinting that an older realtek driver had "speaker fill" option, but i cant seem to find out which version it was. does any one have a realtek chip that they can check the driver to see if it has the speaker fill option?

                        Virtual surround sound is a good choise if you do not want to use many usb ports. It comes in two primary varieties -- normally 2.1 surround and digital sound projection, and recreate the effect of a 5.1 surround-sound system

                          but how does it work? it looks like it is either part of the driver, or a special speaker that acts like a surround sound

                            It's a driver config, not a special speaker. Basically all it does is convert 5.1 to 4.1 or 2.1 to 4.1, or whatever else you want. If you want it, and your Realtek doesn't have it, you'll have to buy an external sound card. If you are worried about available ports then buy a hub.

                              I have used multiple plug-ins to create a 5.1 surround and found at home with SRS Sandbox (http://download.cnet.com/SRS-Audio-S...-10582591.html) I use it on my Home pc and my PC-for-TV. It creates a sensation I cant explain. The fine tuning adjustments greatly influence the way sound is reproduced. All my computers run an onboard 5.1 channel audio and even though Realtek supplies their version, I still like my SRS.
