PSS(4)

NAME
pss - Personal Sound System hardware driver

SYNOPSIS
device pss0 at isa?
device sp0 at pss? port 0x530 irq 10 drq 0
audio* at sp?

DESCRIPTION
The pss driver supports soundcards based on ESC614 or ESC614A ASICs and AD1848 or CS4231 series codecs. Known examples are:

Cardinal Digital Sound Pro 16
Orchid SoundWave 32

The Orchid GameWave 32 is based on the ESC614 ASIC, but is not supported because it does not have a codec.

The pss driver uses the Windows Sound System emulation mode of the ASIC. It is a half-duplex device.

BUGS
This driver doesn't work yet.

The list of cards using the PSS chipset is incomplete.

The ESC614 (version 1) is unable to reliably determine whether DMA channels are free on some motherboards. The ASIC determines that all channels are taken, even if that is untrue. When this happens, the driver cannot verify configured DMA channels with the ASIC's DMA autodetect hardware, so it blindly accepts the user setting.

Cards based on the ESC615 ASIC are not supported.

The MIDI port, joystick, and CD-ROM drive (if present) are not supported.
