NAME

     azalia -- Generic High Definition Audio device driver

SYNOPSIS

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

     options AZALIA_DEBUG

DESCRIPTION

     The azalia device driver is expected to support any PCI device which is compliant to the High Definition Audio Specification 1.0.	Known sup-
     ported controllers are Intel 82801F (ICH6) and Intel 82801G (ICH7).  Known supported codecs are Realtek ALC260, ALC880, ALC882, Analog
     Devices AD1981HD, CMedia CMI9880, Sigmatel STAC9221, and STAC9221D.

SEE ALSO

HISTORY

     The azalia device driver appeared in NetBSD 3.0.

BUGS

     Non-PCM encodings such as Float32 and AC-3 are not supported.

     There is no way to use 20bit or 24bit precision because of a limitation of the MI audio framework.

NAME

     eap -- AudioPCI audio device driver

SYNOPSIS

     eap*   at pci? dev ? function ?
     audio* at audiobus?
     joy*   at eap?
     midi*  at eap?
     options EAP_USE_BOTH_DACS

DESCRIPTION

     The eap driver provides support for the Ensoniq AudioPCI and Creative Labs SoundBlaster PCI series of audio cards.  All models based on the
     ES1370, ES1371, and ES1373 chips are supported.

     By specifying:

	   options EAP_USE_BOTH_DACS

     a second audio device is attached.  You can use it simply by directing audio output to it.  This way it is possible for two different pro-
     grams to use the "same" audio device simultaneously.

HISTORY

     The eap device driver appeared in NetBSD 1.4.

CAVEATS

     The joystick port hardware works by emulating a legacy isa(4) joystick port, bypassing the pci(4) bus method for address allocation.  This is
     unlikely to work on PCI busses other than the primary one.  There is also a possibility for conflicts with real ISA devices because the PCI
     bus is probed before ISA.	Use with caution.
