DCHANGELOG62 - Fixed a bug in handling of full duplex cards in write only mode. This has
87 - Support for OPTi 82C930. Only half duplex at this time. 16 bit playback
146 - Full duplex audio with MAD16+CS4231 may work now. The driver configures
149 duplex mode.
209 - Full duplex support for some CS4231, CS4232 and AD1845 based cards
230 use select() carefully when you are writing a half duplex app.
231 Full duplex mode is not implemented yet.) Select works also with
360 - Now supports half duplex mode. It's now possible to record and
