PSS(4)                    NetBSD Programmer's Manual                    PSS(4)


NAME

     pss - Personal Sound System hardware audio device driver


SYNOPSIS

     pss0 at isa?
     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 chan-
     nels are free on some motherboards.  The ASIC determines that all chan-
     nels 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.
