I had this minor issue with, MoH:AA, but the problem is worse now with Spearhead. Some of the weapons have no sound when I shoot (there will be sound once in a great, great while). It's not a huge deal, but it would be nice to have the sound when I shoot! The weapons with these problems include:

Colt 45 (from mohaa)
Lee Enfield Rifle
Mosin Nagant Rifle
All mortars
Main gun in the T-34

Could be my awesome 3 year old sound card (don't even remember what kind), but I figured it couldn't be that, because why would some sounds work and not the others?
Help would be appreciated.
