.Sh NAME
.Nm wss
.Nd Windows Sound System hardware audio driver
.Sh SYNOPSIS
.Cd "wss0 at isa? port 0x530 irq 10 drq 0 drq2 1"
.Cd "wss0 at isa? port 0x530 irq 10 drq 0 flags 1"
.Cd "wss* at isapnp?"
.Cd "wss* at pnpbios? index ?"
.Cd "audio* at wss?"
.Cd "opl* at wss?"
.Sh DESCRIPTION
The
.Nm
driver supports Microsoft's Windows Sound System, the MAD16 chip based
hardware, and their clones.
.Pp
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 7, 9, 10, or 11, and
the DMA channel may be set to 0, 1, or 3.
.Pp
The device
.Cm flags
must have bit 0 (value 1) set 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.
Chips needing this flag include the OPTi 82C928, 82C929, 82C831, and
the OAK OTI-601D. Setting bit 1 (value 2) in
.Cm flags
disables the joystick port on MAD16 hardware.
