OS/2 Audio device driver for Crystal chipset

CS4231, CS4232 (A, B), CS4235, CS4236 (B, D, E), CS4237B, CS4238B, CS4235, CS4239

DEVICE=\MMOS2\CWAUDIO.SYS

NOTE: for 4231, 4232 and 4236 use 'Mode2' driver version (latest 1.7)

TIP: If you have problems with the Yamaha OPL3-SAx chipset: According to a user, instead of using the Yamaha OPL-3 SAx drivers for the same audio chipset, using the driver for Crystal CS4232 works fine without any limitations.

A free mixer for the crystal cards is LBCSMix V1.0 (lbcsmix100.zip)
