I have a 3d sound problem as well.
So, previously I have had 5.1 sound cofiguration. I was using this fancy Creative x-fi fatal1ty pro PCIe soundcard for output (using all these jack and stuff) and everything was just fine.
Now I have 5.1 as well, but I also have installed the receiver and the sound output comes to it via my videocard (Nvidia gtx750) using HDMI.
The problem is that in the Dark Mod all the sounds come only through frontal and central speakers, rear ones are inactive, even though I have selected 5.1 configuration in game settings. And the sounds which are supposed to come through rear speakers (like footsteps behind you) are played in frontal speakers as well. So it's just like simple stereo. The receiver shows that the imput signal is PCM. The other games work just fine, the problem only with the Dark Mod.
I have OpenAl installed, of course. Any ideas? Thanks in advance.
Upd: my idea is that for some reason in my case the game doesn't really send 5.1 sound to the output device. Or the receiver cannot recognise that it's 5.1 and send it to speakers correctly.
My idea is that for some reason the game
SOLVED: I reinstalled the game and it helped. Not sure what changed, though. Sorry I bothered you, guys.
