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 I/O controller hub (ICH/ICH0/ICH2) and 82440MX
     chipset.  The auich DMA engine supports full-duplex operation and has
     separate channels for line input and microphone.  Unfortunately, simulta-
     neous recording from both line and microphone inputs is not supported due
     to the current ac97(4) design.

SEE ALSO
     ac97(4), audio(4), mixer(4)

HISTORY
     The auich device driver appeared in OpenBSD 2.8.
