NAME    [Toc]    [Back]

     pss - Personal Sound System hardware driver

SYNOPSIS    [Toc]    [Back]

     pss0 at isa? port 0x220 irq 7 drq 6
     sp0 at pss0 port 0x530 irq 10 drq 0
     audio* at sp?

DESCRIPTION    [Toc]    [Back]

     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 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    [Toc]    [Back]

     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.
