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

     audio(4), pci(4) http://www.intel.com/standards/hdaudio/

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.

SND_ICH(4)						   BSD Kernel Interfaces Manual 						SND_ICH(4)

NAME

     snd_ich -- Intel ICH AC'97 and compatible bridge device driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device sound
	   device snd_ich

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   snd_ich_load="YES"

DESCRIPTION

     The snd_ich bridge driver allows the generic audio driver sound(4) to attach to Intel ICH AC'97 and compatible audio devices.

     Some later chips, like ICH6/ICH7, depending on wiring can instead implement newer Intel HD Audio specification, which is supported by
     snd_hda(4) driver.
