    Surround sound issues


    G'day guys,

    I am using an onboard VIA High Definition audio device on my M2N68-CM motherboard and wish to connect the sound system from my TV to my PC. I have plugged each speaker into the DVD player/main unit. I then plugged a Y adapter from the red and white AUX IN ports on the main unit into the green jack on my sound card. It seems only two speakers work, the left and right speakers - the sub and center and remaining speakers do not work.

    Any ideas?
    Thanks a lot.

    EDIT: It's not actually the sound system from my TV, but the sound system i was using for my TV.

    There's your problem. You're dropping down to two channels. Composite [Red/White/Yellow] is not multichannel like HDMI or Optical because it is purely analog and there just isn't enough room for multiple signals.

    To get surround sound, you'll need a surround receiver that has at least 5.1 channels of output AND input. You can convert the 3.5mm from your PC's jacks to Composite, as long as you keep the same quantity of channels.

    Well that's strange because my other surround system works the same way and works flawlessly.

    How do I go about getting a surround receiver and converting the 3.5mm from my PC's jacks.

    Some surround systems let the L/R channels bleed into the rear-L/rear-R channels as well as mix them in the C channel. I'm using NewEgg as an example but here's some receivers that aren't to crazy priced. [Some brands like Onkyo are the high-enders]

    Newegg.com - Receivers, Home Theater Receiver, Stereo Receiver, AV Control Receiver, 7.1 Receiver

    This is what you could use for turning 3.5mm into RCA

    Newegg.com - Cables To Go 40423 6 feet 3.5mm Stereo Male to Two RCA Stereo Male M-M

    If you take a look at the back of a receiver, you can see where all of the inputs reside

    Newegg.com - Computer Parts, PC Components, Laptop Computers, LED LCD TV, Digital Cameras and more!

    In the image above, the channels you would have running from you PC [sub, center, etc] are below and to the right of the Monitor Out jacks. Receivers are full of jacks so whichever one you choose, make sure you read the book.
