Sound drivers for Crystal PCI sound chips BETA
http://hobbes.nmsu.edu/pub/incoming/cwos2311.zip
From: Roland Reimers (
There are more recent versions available, but not from the Crystal website. Since some IBM Thinkpads have Crystal soundchips the drivers have been develeoped further by IBM. You can get the most recent official version from here (v 3.10 file name: aftpitos.exe):
In December 2001 a version 3.11 appeared for a short time on IBM testcase.
I am using this version with OS/2 4 fixpack 12 so far without any problems. Since it is no longer available from testcase, I have uploaded it to Hobbes incoming. So, hurry up !
