NAME
     auich - Intel 82801AA/AB/BA and 440MX PCI audio driver

SYNOPSIS
     auich* at pci? dev ? function ?
     audio* at auich?

DESCRIPTION
     The auich driver provides support for the AC97-based audio present on the
     Intel 82801AA/AB/BA/CA I/O controller hub (ICH/ICH0/ICH2/ICH3) and
     82440MX chipset.  The auich DMA engine supports full-duplex operation and
     has separate channels for line input and microphone.  Unfortunately, si-
     multaneous recording from both line and microphone inputs is not support-
     ed due to the current ac97(4) design.

SEE ALSO
     ac97(4), audio(4)

HISTORY
     The auich device driver appeared in OpenBSD 2.8.
