WSS(4)		      OpenBSD Programmer's Manual (i386)		WSS(4)

NAME
     wss - Windows Sound System audio device

SYNOPSIS
     wss0 at isa? port 0x530 irq 10 drq 0 flags 1
     wss* at isapnp?
     audio* at wss?

DESCRIPTION
     The wss driver supports Microsoft's Windows Sound System, MAD16 chip
     based hardware and their clones.  The Windows Sound System is a half-
     duplex device.

     The base I/O port is set by a jumper on the board; valid choices are
     0x530, 0x604, 0xE80, or 0xF40.  Both IRQ and DMA channels are software
     programmable.  The IRQ may be set to 5, 7, 9, 10, or 11, and the DMA
     channel may be set to 0, 1, or 3.

     The configuration file must have bit 1 set in flags to enable the MAD16
     support.  This is to avoid potential conflicts with other devices when
     probing the MAD16 because it requires use of extra I/O ports not in the
     base port range.  Bit 2 in flags disables the joystick port on MAD16
     hardware.

BUGS
     The FM synthesizer is not supported.
