Latest revision as of 16:50, 2 October 2025

Part of Universal Audio Driver (UniAud).Uniaud32.sys is the actual audio driver that connects to the hardware and makes it work. It consists of a modified ALSA core and some OS/2 specific pieces which make it load and run on an OS/2 system.

Supports the following audio cards:

Sound Blaster Live!
Cirrus Logic CS4281 chipset based audio cards
Avance Logic ALS4000 chipset based audio cards
C-Media CMI8738 chipset based audio cards
Intel ICHx + SigmaTel STAC9721/23 chipset based audio cards

NOTE: Uniaud will crash if EARLYMEMINIT=TRUE is in the config.sys
