Open Sound System for AIX

OSS/AIX provides device drivers for popular soundcards under IBM AIX 4.x. OSS/AIX comes with a user-friendly configuration tool that makes adding and configuring sound cards into IBM AIX a snap. OSS/AIX complies with the Open Sound System API. OSS/AIX also supports the onboard audio hardware for all IBM and Motorola PowerPCs.

OSS/AIX provides support for Java audio and IBM's Ultimedia Services. Now you can run UMS on any sound card!.
