Appendix G: A Note on Windows Sound System
Windows Sound System provides 16-bit 44.1 KHz stereo record and play
back with OPL3 FM synthesis for DOS game support in a DOS window.
Settings for Windows Sound System may be chosen when selecting Driver
Setup in the Windows Control Panel. These settings are as follows:
DUPLEX .
Half-duplex allows for either playing or recording.
Full duplex allows simultaneous playing and recording at the same
sample rate.
Enhanced is the same as full duplex, but simultaneous playing and
recording may occur at different sampling rates.
The default is full-duplex.
I/O Address . The default is 530h.
DMA Channel . The default is 1 for Play and 0 for Capture. NOTE: you
may use the same DMA as your Sound Blaster. DMA Channel is not active
in Windows.
IRQ . IRQ10 is the best choice. If you select IRQ9 or IRQ11, DOS-based
games will not be supported in a DOS window.
