# 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.
