    5.1 Channel Audio - Sound only from Front Left and Right Speakers


    Dear all,

    I have been reading 1000s of posts on the net for 5.1 Channel speakers giving outputs only through the front left and right speakers. Well, I am no exception

    - Connected all the cables correctly to the respective jacks... but still...
    - Tried atleast 5 different of HD Audio Drivers (including the latest by the onboard device maker VIA - v10_1200a, as well as the Microsoft generic HD Audio driver)... Installed, Completely wiped, Reinstalled, all possible combinations... but still...
    - Tried adding the Sound Blaster 5.1 Channel PCI Card (SB 5.1 VX)... but still...
    - Tweaked all possible 'Playback Devices' options... but still...
    - Tried different 5.1 Channel testing audio files... but still...

    But still still my speakers (brand new iBall MJ04 - iBall's latest model) doesn't play 5.1 Channel Audio

    Following is my system specifications:

    CPU - Intel Core 2 Duo E8200 @ 2.66GHz
    Package (platform ID) - Socket 775 LGA
    Mainboard Model - P5KPL-CM
    Northbridge - Intel P35/G33/G31 rev. A2
    Southbridge - Intel 82801GB (ICH7/R) rev. A1
    Onboard Audio - VIA VT 1708B, 8-CH High Definition Audio
    Memory Type - DDR2
    Memory Size - 4096 MBytes
    OS - Windows 7 Ultimate (64 Bit)

    Though this board supports 8 Channel audio, even 5 Channel is not being played.... when an audio file or video file is played, all speakers flare up.... playing the audio is all speakers... this is NOT 5.1 channel audio... this is just 'Speaker Fill'.... playing the same sound in all the 5 speakers.... tried disabling 'Speaker Fill' option in the VIA Audio Panel.... NOTHING WORKS

    After reading through 1000s of posts on the net about this issue, I think I have no other option, but to change/upgrade my mother board.... so... please advice me:

    1. Which motherboard (that is compatible with my processor) will play genuine 5.1 channel audio when run on Windows 7 ???

    Intel lists the following Compatible Chipsets
    Intel® G31 Express Chipset
    Intel® G33 Express Chipset
    Intel® G35 Express Chipset
    Intel® P35 Express Chipset
    Intel® Q33 Express Chipset
    Intel® Q35 Express Chipset
    Intel® X38 Express Chipset
    Intel® P31 Express Chipset
    Intel® G45 Express Chipset
    Intel® P45 Express Chipset
    Intel® X48 Express Chipset
    Intel® G43 Express Chipset
    Intel® P43 Express Chipset
    Intel® Q43 Express Chipset
    Intel® Q45 Express Chipset
    Intel® G41 Express Chipset

    Which among the above will really play GENUINE 5.1 Channel audio ?

    2. If anyone has other suggestions than changing the motherboard, please let me know....

    Awaiting some 'REAL' help

    Pramod.

    I assume you are using something like this,

    5.1 Channel Audio - Sound only from Front Left and Right Speakers-82-021-058-04.jpg

    or similar cables to connect from the 6 RCA input jacks on the system to the 3 mini jacks on the computer (one each for the front left/right, sub/center and rear left/right).

    Also is the audio you are trying to play stereo or 5.1? If it is only stereo then it requires using speaker fill to get sound from all speakers.

I got a new computer, and it appears the integrated sound card does 100% well on my 5.1 speakers.

Problem is that my speaker system only has 1 audio...
Hey guys, I seem to be having an issue with my onboard sound card. It's a VIA card built into the Asus M4A785TD-M EVO motherboard. It seems to be that my left channel is roughly 20% of the volume of the right, even at 100%. The channel works because I can hear it, but it's not nearly as loud...
