I am using Version 1.51 of Rome: Total War and Version 1.61 for Rome: Total War Barbarian - Invasion. My There are five Sound Provider's that Rome: Total War and Rome: Total War Barbarian - Invasion allow you to use. They are: DirectSound 3D SOFTWARE EMULATION (worst one), DirectSound 3D HARDWARE SUPPORT, CREATIVE LABS EAX 3 (TM), CREATIVE LABS EAX 2 (TM), and MILES FAST 2D POSITIONAL AUDIO. I only have access to the first and last options even though I have a great sound card (a Sound Blaster Audigy Rx/5 with latest drivers).
I have reverified my games files in Steam, cleared Steam's download cache, and have the latest Window's updates (which were the suggestions I got from SEGA support).
Does anyone know how I can fix this? Also, if there is any additional info required please ask.
