.Nd NeoMagic MagicMedia 256 audio device driver
|
|
.Sh SYNOPSIS
|
|
.Cd "neo* at pci? dev ? function ?"
|
|
.Cd "audio* at audiobus?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the NeoMagic MagicMedia 256AV and 256ZX
|
|
AC'97 audio devices, found on many laptops.
|
|
.Pp
|
|
The MagicMedia 256AV also comes in a variant (usually found on Dell
|
|
and HP laptops) that works in Windows Sound System emulation mode,
|
|
not in AC'97 mode. That variant of the chip must be used with the
|
|
.Xr wss 4
|
|
driver. The
|
|
.Nm
|
|
driver will not attach to such chips.

|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver appeared in
|
|
.Nx 1.5.1 .
|
|
.Sh BUGS
|
|
The MagicMedia 256 series is not well-documented.
|
|
.Pp
|
|
No MIDI or FM synthesizer capability is provided with the MagicMedia 256
|
|
in AC'97 mode. While those capabilities are provided by the Windows driver
|
|
for the chip, they are emulated by the Windows driver, and not directly
|
|
supported by the hardware.
