    5.1 system problem

    dorudm

      Hi,


      I have a strange problem on my PC(DG45ID motherboard) with Windows 7 Proffesional x64.

      I have a 5.1 system conected to my integrated soundcard, which is properly connected and set in the IDT software. If I test the speakers from this a sound can he heards in each of the speakers but in normal use only 2 speakers can be heard(in winamp/wmp/gom player ... whatever).

      All speakers also work in some games I played (e.g. Splinter Cell Conviction).

       

      If someone can help me in this it would be great.

       

      thx

          SPI/DF is two chanel you have to have a decoder to get 5.1 . I Know what you mean ,I have a Logitech Z-5500 5.1 and it's connected by a Toslink cable But the Logitech sys decodes it into 5.1.

            How are you finding the latest IDT Drivers as far as stability goes, if you enable Dolby Digital in the control panel software - especially if you use it like this over an extended period and try playing around with things like volume sliders etc. Is it all rock solid on your DG45ID Robert? What motherboard rev do you have this hooked up to?

                My sound card should be a 5.1 one so why should I need something else?

                Indead if I enable Dolby Pro Logic IIx all of them work but the quality is much lower then it should normaly be.

                      Does it support Dolby Digital II, THX ,DTS 96-24 .??

                        dorudm, according to the Genius Website there's no mention of Dolby Digital support for the V2 of this product (can't imagine V1 had it either). This means it'll be a case of having to use the analog (wire) cables plugged into their respective sockets to get 'surround sound' where the media being played calls for it.

                        parsec wrote a very detailed (and helpful) explanation of things related to surround sound, Dolby, DTS etc over in this thread - it's well worth a read.

                         

                        Robert, thanks for the mobo version - are you finding Dolby Digital to work reliably with your DG45ID and IDT driver software or is the software a little shaky when DD is enabled? You're one of few here using this board with a DD speaker arrangement hence my butting in to ask how it's going for you (sorry dorudm).

                          @Robert:

                          You lost me with these questions

                           

                          The strange thing is that the system works ok in games, e.g. Splinter Cell.

                          This is the strangest thing, why it works ok in games.

                           

                          I tested the audio system on a laptop with 5.1 sound card and it worked great from start.

                           

                          Thx.

                            dorudm, please have a read of the (quite long) post by parsec in that thread I linked to (just click the link) and you'll find an explanation of some of the terms Robert referred to - take your time and it should make sense.

                             

                            As for why not all the speakers are working all the time, it's because that is up to the software/game/DVD Player etc to call however many speakers it wants to do its thing. Without all the components working together to achieve 5.1 sound, it'll default to only a subset of all the speakers. From having a read of the wikipedia website relating to Dolby Pro Logic II, it appears that the reason why the sound quality using this feature over all the speakers isn't as good as what you get out of plain stereo, it's because the system software where you selected Dolby Pro Logic II has to chop up the sound intended for two speakers (eg what comes out of your sound playing software) and 'water it down' (for want of a better term) to suit 5.1 speakers. It's different if you have software that's programmed to output 5.1 seperate channels of sound to begin with (as per the game you mentioned) because that software will take account of precisely what sounds it'll want in each speaker.

                              It's been working fine , I even took it downstairs and hook it up to my Yamaha RX-800 , The 5.1 works great when hooked up to a high end reciver.

                                  Thanks for that. I guess because you're using the receiver to adjust volume etc, you wouldn't be giving the PCs mixer and IDT Control panel software a good workout?
