Speaker setup
- Many games use the speaker configuration reported by the operating system so having it set correctly is crucial.
Issues fixed
Sound problems (cracking, delays, missing music/effects, etc.)
No surround sound
- Some games are using old implementation of DirectSound or other sound libraries that result with no surround sound on Windows Vista and newer.
- See also Restoring Legacy Audio Effects (Direct Sound 3D) as these solutions may also restore surround sound functionality if the issue is with a game developed before 2008.
Game volume decreases
Can't enable EAX
- EAX effects need a workaround on Windows Vista and newer.
- This might not work for some games using EAX.
Please refer to Restoring Legacy Audio Effects (DirectSound 3D) for more information.
CD music not playing
CD-DA music (shows up as a music CD in media players)
Non-CD-DA music (does not show up as a music CD in media players)
Restoring Legacy Audio Effects (DirectSound 3D)
DirectSound is a deprecated component of DirectX. DirectSound 3D was a component of DirectSound that allowed games to use hardware-based audio enhancement features of discrete sound cards. Many Windows-based games developed before the public release of Windows Vista (January 2007) used hardware-accelerated audio effects that are no longer supported in Vista and newer Windows operating systems due to changes made with how Windows handles audio. To resolve this incompatibility, sound device manufacturers developed software to restore legacy audio effects for their respective devices and end users developed workarounds that can be applied to any sound device.
EAX
- Using these solutions may also restore surround sound functionality in games that use DirectSound 3D.
A3D
- Lists of Aureal 3-Dimensional enabled games can be found here and here
- C-Media based sound cards support A3D 1.0 out of the box, even in Windows Vista (via Xear3D)[1]
