When the sound card uses a custom driver for use with the system supplied port class driver PortCls.sys or implements a mini-driver for use with the streaming class driver, applications can bypass the KMixer completely and use the kernel streaming interfaces instead to directly interact with audio driver and reduce latency. Windows 98 includes ...
DirectSound is a deprecated software component of the Microsoft DirectX library for the Windows operating system, superseded by XAudio2.It provides a low-latency interface to sound card drivers written for Windows 95 through Windows XP and can handle the mixing and recording of multiple audio streams.
It was one of the first PCI sound card solutions to offer MS-DOS legacy compatibility without special hardware extensions to the standard PCI slot. When paired with a capable codec , such as the AK4531 (pre-AC'97), the ES1370 supported the then-latest in 3D audio positioning through 4-speaker surround sound.
The Sound Blaster Pro was fully backward compatible with the original Sound Blaster line, and by extension, the AdLib sound card. The Sound Blaster Pro was the first Creative sound card to have a built-in CD-ROM interface. Most Sound Blaster Pro cards featured a proprietary interface for a Panasonic (Matsushita MKE) drive. The Sound Blaster Pro ...
VDMSound was an open-source (licensed under GPLv2) emulator of legacy sound card devices, designed to allow video games and other applications written for MS-DOS to run on the Microsoft Windows NT/2000/XP/95/98/Me operating systems. Its author is Vlad Romascanu. [1] [3]
Most Sound Blaster 16 cards feature connectors for CD-audio input. This was a necessity since most operating systems and CD-ROM drives of the time did not support streaming CD-audio digitally over the main interface. The CD-audio input could also be daisy-chained from another sound generating device, such as an MPEG decoder or TV tuner card.
WSS 1.0a drivers were released in February 1993. They introduced single-mode DMA, supported games in MS-DOS, Ad Lib and Sound Blaster emulation. [4]WSS 2.0 drivers, released in October 1993, added support for OEM sound cards (Media Vision, Creative Labs, ESS Technology) and included an improved DOS driver (WSSXLAT.EXE) that provided Sound Blaster 16 compatibility for digital sampling.

The AWE64D was not quite compatible with AWE64 PCI drivers, however, and had to use separate driver packages. An AWE64 Mark II was also designed, and prototype boards and drivers made. This card added 4 speaker surround sound for games, and a hardware Dolby Digital decoder. The six extra phono plugs (sub, center, left rear, right rear, digital ...
