     audio* at audiobus?

DESCRIPTION

     The bba driver provides support for the IOASIC baseboard audio found on DEC 3000/300, 3000/500 (NetBSD/alpha) and DEC Personal DECstation
     (NetBSD/pmax) systems.  The baseboard audio driver is based on the AMD 79c30 ISDN and audio interface.  The interface is only capable of
     playing and recording 8kHz mu-law audio.

NAME

     neo -- NeoMagic MagicMedia 256 audio device driver

SYNOPSIS

     neo*   at pci? dev ? function ?
     audio* at audiobus?

DESCRIPTION

     The neo driver provides support for the NeoMagic MagicMedia 256AV and 256ZX AC'97 audio devices, found on many laptops.

     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 wss(4) driver.  The neo driver will not attach to such chips.

SEE ALSO

     ac97(4), audio(4), intro(4), midi(4), pci(4), wss(4)

HISTORY

     The neo device driver appeared in NetBSD 1.5.1.

BUGS

     The MagicMedia 256 series is not well-documented.

     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.
