pss - Personal Sound System hardware driver
pss0 at isa? port 0x220 irq 7 drq 6
sp0 at pss0 port 0x530 irq 10 drq 0
audio* at sp?
The pss driver supports sound cards 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 not
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.
audio(4), intro(4), isa(4), wss(4)
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,
cannot verify configured DMA channels with the ASIC's DMA
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
