so i have an amplifier that is able to amplify 4 speakers and a powered subwoofer.but it only seems to have left and right because it doesn't have a decoder for surround sound.so when i try to go in realteck audio and i set audio to quadrofonic(2 in the front and 2 in the back) and i do the test,when it sends sound to the left front speaker,my left front speaker and left back speaker make sound,same with the right speakers.and when it tests the back speakers,nothing makes sound at all.
does anybody know how i can solve this problem with maybe using my speaker cables that are + and - putting in a different order because i know that's possible but not for the surround effect i want.maybe an externel surround decoder>thanks for the help
I have a Sony KP-46WT520 HDTV and take the stereo outputs and feed my very good stereo system for great stereo sound quality.
But I see a lot of shows have 5.1 Surround Sound. I see complete 5.1 audio systems you can buy for this format for $500 and up. That's 1/3 of what I paid for the whole HDTV. I also have spare speakers that will make fine side and rear speakers.
All I want is a way to decode the sound and make my own system. I can buy the amps for these channels at Radio Shack for under $100, probably under $50.
Can I buy just a decoder? If so where?
Simple-to-use software application that helps you encode AC3 and WAV files, and decode MP3s which can be turned to AC3 tracks with different bitrate values
Sound quality is paramount for anyone who enjoys listening to music and watching movies onto their home computer. For this reason, having the appropriate tools for decoding audio streams and encoding the sound to obtain the best output possible is a must.
Aud-X 5.1 Surround Codec is one such utility, easy to install and not at all difficult to set up, even by less experienced users. This particular codec has a configuration area that will make it possible for you to adjust the encoding and decoding settings in a quite simple manner.
Encoding settings
The quality for audio encoding starts from 80kb/s, or streaming quality, and can reach 192 kb/s, which is the highest possible level for this utility. Aud-X 5.1 Surround Codec supports AC3 and WAV file formats for this operation and you can easily choose the track to process by pressing the 'Encode file' button.
Decoding options
Insofar as decoding sound files is concerned, the software application can handle MP3s which can be turned into AC3 tracks with bitrates from 128 up to 640. Also, Aud-X 5.1 Surround Codec is able to decode tracks into PCM format, namely 6 channel uncompressed audio files.
Extra configuration settings
There are even more configurations you can tinker with and they are related to the Aud-X DirectShow filter. Thus, by checking the corresponding box, you will be able to set this codec as the default one for decoding AC3, PCM, MP3 as well as all Aud-X streams.
In case you have other decoders installed onto your system and still want Aud-X 5.1 Surround Codec to handle one of the above mentioned formats, the filter will become the last chain in the processing of the streams.
Bottom line
All things considered, when it comes to transforming regular movie soundtracks or music files into amazing surround audio, this particular software program may prove to be just what you need. Easy-to-customize and with a decent feature set, Aud-X 5.1 Surround Codec is a really good choice and is suitable for all users, regardless of their experience in sound processing.

I've been searching the internets for answers to my questions for some time now, but all my findings have been very inconclusive. Either it seems I'm trying to do something that no-one else in the world has ever wanted to do before, which would be pretty weird, considering what it is, or the answer must be so obviously simple that I'm completely missing something. That would also be strange in this case, since I've been into HiFi and home-cinema audio for over ten years, and like the technical side of it. I'm also good at my PC-stuff, been building my own for many years, and am just as interested in that.
Anyhow, firstly, what I'm trying to do, and I can explain why I want to do this in just this way later:
I want to take a digital surround audio stream, either Dolby Digital or DTS (needs to support both, and work with the newer HD-formats) from for example an Xbox or TV-box. Not sure here if I need PCM, or only AC3? This over an optical cable. Into either some dedicated decoder, or into an optical input on my PC. Decode the signal, and get the surround outputted via preferably RCA connectors, but 3,5 mm jacks would also work. Then into my analogue 5.1 input on my amp, and onto my speakers. So:
DD/DTS - Optical - PC/Decoder - Analogue 5.1 RCA or 3,5 mm - Amp - Speakers.
Now, I have an optical input on my Creative Sound Blaster Z, but that only supports stereo audio, and can't decode DD/DTS. Seems a few older Sound Blasters and a few other sound cards may support decoding, but I still haven't seen any solid answers as to what will work, and without loads of tweaking with different software and stuff, without severe lag in the audio-stream. Dedicated home cinema surround-processors are awesome, and do exactly what I need, but they are very expensive, since they are almost always high-end, and many times cost as much or more than the flagship surround-receivers.. Also, they have limits, they do get old. And computers are a lot more flexible and easier to adapt to new technologies, be it a new connector or audio format. So I'd rather invest in my PC for this as well.
If you need to know why I have to have analogue 5.1, it's pretty simple, my amp is not a home-cinema receiver, but rather a complex balanced stereo-amp, in pretty much the upper HiFi segment. Balanced meaning, to simplify this, that it separates the signal all the way, effectively doubling the components in the amp. So in balanced 2-ch mode, there are 4 power-amps in use. The manufacturer then had a genius idea (that never caught on with others) to add one more extra power amp, and 5.1 analogue inputs. And the ability to switch between unbalanced 5 channel mode and fully balanced 2-channel using the remote control. So in a way what it is is an integrated balanced 2-channel HiFi amp, that plays in the league of the pros, but it's also with the press of a button a very competent 5-channel amp, without any digital processing.
But enough of that, there are others who want analogue surround solutions for different reasons, so I know I'm not completely alone in this.
What would I need to make my PC a working digital audio decoder, using external sources? Seems odd that it should be so hard to find this in 2014, but oh well.
All help would be greatly appreciated! Hope you made it through all that text.. =)
