I recently purchased a new computer with the following motherboard:
ASUS P5N32-E SLI Plus Which comes with a SoundMax sound card.
Everything seems to be fine, all the cables are connected properly.
I know this because when I run the SoundMax test
all 5 speakers play the test sound. Once it comes to playing anything else it plays in 2.1
I've checked all sound settings, I've checked audio settings in my programs and they're all set correctly.
I don't know who's to blame, Windows or SoundMax.
SoundMax's website basically tells you "It's asus' problem". Asus' website has no support topic on this. I tried googling for help but I can't seem to find relevant results.
side note: SoundMax's software
interface and it's features suck donkey dick. Just putting it out there for potential buyers.

Perhaps the application/game doesn't support 5.1?
Applications that I know support 5.1 because they worked on my old PC.
I upgraded my drivers and all that jazz in case anyone asks.
The speakers are Logitech X-530, basically standard headphone plug size.
I set the rear channel volume as high as it can go and offset it by lowering the other channels but it's just not cutting it. I've done further research and it turns out it's quite common.
Seems to be more prominent on Windows Vista and isn't limited to SoundMax sound cards.
Possible causes:
nvidia nforce
windows upmixing
soundcards just refusing to play stereo audio
and winamp and other applications only support more speakers when you're using 5.1 source material, like a SACD or DVD audio.
if you want 2 channel stuff UPMIXED to your 5.1 speaker set, you have to turn on upmixing somewhere, handled by the audio driver/program/card
pray you can find it in the soundmax thing. Creative calls it "CMSS-3DSurround" for example and it is something you have to enable and adjust.
if NOT, your speakers have a crappy upmixing ability, by pressing the matrix button.
le sigh
Audio from youtube plays only on the center channel.
I think it's because it's mono audio.
