I recently got Vegas 2 off of Steam. But everytime I load it up and play any of the games modes the only audio I can hear is my characters speech and gunshots. I can not hear any of the audio created by other characters or enemies. I've already tried reinstalling. If I am unable to sort this issue out, I will most certainly never give Ubisoft my business again.

Here is my specs:
Operating System: XP
Processor: Intel Petium 4 CPU 3.00 GHz (2 CPUS)
memory: 1534 RAM
Display: ATI Radeon HD 2600 PRO
Sound 1:SoundMAX Digital Audio
Sound 2: ATI HD Audio rear output

What is your sound setup?(eg. stereo, 2.1, 5.1, et cetera)

Is the game set to project sound in the same manner as your speakers are set up?

Stereo headphones

Is your ingame sound setting set to stereo?

The only settings in-game I see are microphone settings as volume adjustment.
