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.
