  1. Hiya, Ive got problem with my speakers 5.1. The problem is that theres only 2 speakers working and 3 others are not working at all. When I do the test speakers theres test-sound in all my speakers, but when I do listen to music, unfortunately only 2 of em are working properly. Its kinda weird imo.
    My motherboard is ASRock G31M-GS.

    If anyone can help, Id be very thankful.

    Check your sound settings. They may be set to 2.1 instead of 5.1.

    that's because your music are only recorded in stereo 2-channel format. turn on Realtek Speaker Fill / Dolby ProLogic IIx to upmix it to give sound to all 5 speakers. or try this one instead.

    Where can I get Realtek Speaker Fill or Dolby ProLogic IIx?

    According to your mobo specs, you have this onboard sound card:
    - 5.1 CH Windows® Vista™ Premium Level HD Audio (ALC662 / VIA® VT1708S Audio Codec)

    If you installed everything, or it came preinstalled, you should have some kind of audio panel which you'll find in the lower corner.


    I happen to have dedicated sound cards on both of my computers, so I can't show you any examples for your hardware, but there should be some kind of audio program installed. Click on that program, and you'll find settings. Play around with those until you find something that upmixes music, you should see something which says Dolby, etc.

    If you're using Realtek in Win Vista / 7, go to realtek hd audio panel

    or in the sound control panel

    If your realtek supports Dolby ProLogic IIx instead of Speaker Fill, it would be in the Dolby tab in the second picture. You should now hear sounds from your rear speakers. It would not be the same as the front speakers though.

    Wow, nice. I had run into this issue before and had to use a Winamp plugin to get around it. This plugin was buggy and actually doubled the bass output for some reason. (Which was kinda awesome :D)

    I will be testing the moment I get home from work.

    Thanks nismo91

    if you're open to alternatives, check out the ChannelMixer from foobar2000 here. the reason i recommend it is because I can manipulate the settings for the rear speakers. so i am not stuck with the fixed preset on Speaker Fill or Dolby ProLogic IIx.
