OK, I'm experiencing a pretty strange sound problem. Yesterday, I noticed that I no longer had certain sounds in the game. I can no longer hear my guns firing, flaps being deployed or retracted, gears going down, hits on my plane or the sounds of the puffy acks exploding near my plane. It's only these sounds, all others work fine. I've uninstalled AH and all sound packs, reinstalled AH with the default sounds and same problem.
Thought it might be center channel and I've run a diagnostic program that comes with my Audigy 2 ZS sound card. At least in that diagnostic, my center channel is working and as far as I can tell, in all other games as well. I've also run the DXDiag sound test and again, center channel is putting out sound.
I'm kind of stumped.
