I used the old drivers 3.58 and it fixed my problem, infact the rear sound problem was on medal of honor and all the other games, the sound test did show it worked (k8nspro soundman), but in games i got nothing from rear, so i used the 3.58 to see if it was driver related and it fixed it :)

I actually played through HL2 with my previous mobo which had Soundstorm and 5.1 worked fine but when i reinstalled HL2 after updating my CPU/Mobo the 5.1 never worked so i had a look at Steam Tech Support and that was thier suggestion as well :)

This still didn't fix the problem fully for me. Sure all of the speakers work now but the sound is the same from all of the speakers.

Mines ok, when i turn 180 degreees from the source of the sound i can hear the sound move from the front speakers to the rear speakers.

Well, i have a soundmax onboard implementation... i noticed in advanced sound settings, I had 2 -> 6 channel spread turned on.. turned that off and the surround sounds worked properly.

my sound works okay, but i dont use realtek drivers, i use the nforce audio drivers.

Well i have a k8nspro (gigabyte) use the 3.58 drivers for audio, this one i know with 100% confirm that the rear speakers work. Its the latest one that dosen't work, i dont have past driver versions to test nor do i have the time...plus the new one hardly fixes anything in the quality so what bother :/

Heres the thread on this at the steam forums:

Not sure if the AC97 cards are fixed or not for this, but the HD Audio cards are still affected. This entire issue is actually mostly valves fault for not sticking to the direct3d spec. Several sound card manufacturers are forced to work around it.
