.Sh NAME

|
.Nd Personal Sound System hardware driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device pss0 at isa?"
|
|
.Cd "device sp0 at pss? port 0x530 irq 10 drq 0"
|
|
.Cd "audio* at sp?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports soundcards based on ESC614 or ESC614A ASICs and AD1848
|
|
or CS4231 series codecs. Known examples are:
|
|
.Pp
|
|
.Bl -tag -width -offset indent -compact
|
|
.It Cardinal Digital Sound Pro 16
|
|
.It Orchid SoundWave 32
|
|
.El
|
|
.Pp
|
|
The Orchid GameWave 32 is based on the ESC614 ASIC, but is not
|
|
supported because it does not have a codec.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver uses the Windows Sound System emulation mode of the ASIC.
|
|
It is a half-duplex device.
|
|

|
|

|

|
|
.Sh BUGS
|
|
This driver doesn't work yet.
|
|
.Pp
|
|
The list of cards using the PSS chipset is incomplete.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
Cards based on the ESC615 ASIC are not supported.
|
|
.Pp
|
|
The MIDI port, joystick, and CD-ROM drive (if present) are not supported.
