DirectSound was the component responsible for audio in [[DirectX]]. Most of games developed since mid-90s always relied on its hardware-based audio path to offload work and make use of the various enhancement features of discrete [[Glossary:Sound card|sound cards]]. With the arrival of Windows Vista and its new audio stack, Microsoft deprecated it and just employed a software emulation layer. Depending on each game results may vary from the absolute consistency to bad, misplaced or even missing 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.

Speaker setup

Many games use the speaker configuration reported by the operating system so having it set correctly is crucial.
Instructions

Issues fixed

Sound problems (cracking, delays, missing music/effects, etc.)

Instructions
Instructions

No surround sound

Some games are using old implementations of OpenAL or other sound libraries that result in no or bad audio positioning.
See also: Restoring Legacy Audio Effects (DirectSound 3D). The majority of old (pre-2008) games used to use DirectSound3D hardware acceleration to determine positional audio
Instructions

Game volume decreases

Instructions

Can't enable EAX

EAX effects need a workaround on Windows Vista and newer.
This is not required for games using OpenAL

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)

Enabling 7.1 Output In Source Engine Games (Windows Vista and newer)

While many of Valve's games that use the Source Engine may have a 7.1 speaker option, this feature may not function correctly in Vista and newer Windows operating systems. When set to 7.1 output, the game will output to only 5 speakers, leaving the side surround speakers void of sound. This issue is typically present in Source engine games that use Miles Sound System.

Instructions

Restoring Legacy Audio Effects (DirectSound 3D)

DirectSound was the component responsible for audio in DirectX. Most games developed since the mid-90s relied on its hardware-based audio path to offload work and make use of the various enhancement features of discrete sound cards. With the arrival of Windows Vista and its new audio stack, Microsoft deprecated it and just employed a software emulation layer. Depending on each game, results may vary from absolute consistency, to bad, misplaced or even missing 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.

Instructions

EAX

Using these solutions may also restore surround sound functionality in games that use DirectSound 3D.
If the game has a grayed-out or disabled EAX option, using these solutions should allow the option to be enabled.
