PSS(4)                  BSD Programmer's Manual (i386)                  PSS(4)


     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 supported be-
     cause 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 chan-
     nels 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.
