With Microsoft's decision to remove the audio hardware layer in Windows Vista, legacy DirectSound 3D games will no longer use hardware 3D algorithms for audio spatialization. Instead they will have to rely upon the new Microsoft software mixer that is built into Windows Vista. This new software mixer will give the users basic audio support for their old Direct Sound games but since it has no hardware layer, all EAX effects will be lost, and no individual per-voice processing can be performed using dedicated hardware processing.

EAX has become the de facto standard for real-time effects processing. It has been incorporated in hundreds of games and has become the method of choice for game developers wanting to add interactive environment effects to their titles. Some of the best selling games of all time use the EAX extensions to DirectSound 5.0 and beyond, including Warcraft3, Diablo2, World of Warcraft, Half Life, Ghost Recon, F.E.A.R. and many others. Under Windows Vista, these games will be losing the hardware support that came as standard under the previous Windows Operating Systems, and will no longer provide real-time interactive effects, making them sound empty and lifeless by comparison to the way they sound on Windows XP.

The good news for owners of advanced audio cards like SoundBlaster X-Fi is that the developer community has been preparing for this for over 3 years. Hardware audio will not be disappearing with the launch of Windows Vista. Games that support OpenAL today will continue to provide full hardware-enhanced 3D audio under Windows Vista. This includes games such as Battlefield 2, Doom3, Unreal Tournament2k4, Dungeon and Dragons Online, Prey, Quake 4, and many others (a full list can be found at http://www.openal.org/titles.html). These games have complete hardware-based HRTF support for multiple speaker and headphone setups as well as full support for all the different versions of EAX. Also, these games will be able to take advantage of the hardware-accelerated path on supporting hardware for performance and quality increases.

Wow I dont understand why on earth would Microsoft removed hardware sound layer? Hardware sound do better job while CPU usage is low than in software all done by the CPU with high CPU usage. That will spell bad news for all integrated sound on motherboards and all old sound cards like Audigy 2 and below.
