AUICH(4)                   BSD Programmer's Manual                    AUICH(4)

NAME

     auich - Intel 82801AA/AB/BA/CA/DB/EB, 82440MX, and compatibles PCI audio
     driver

SYNOPSIS

     auich* at pci? dev ? function ? flags 0x0000
     audio* at auich?

DESCRIPTION

     The auich driver provides support for the AC97-based audio present on the
     Intel 82801AA/AB/BA/CA/DB/EB I/O controller hub
     (ICH/ICH0/ICH2/ICH3/ICH4/ICH5), 82440MX chipset, SiS 7012, AMD 768, AMD
     8111, NVIDIA nForce and nForce2 chips. The auich DMA engine supports
     full-duplex operation and has separate channels for line input and micro-
     phone. Unfortunately, simultaneous recording from both line and micro-
     phone inputs is not supported due to the current ac97(4) design. Setting
     flags to 0x0001 will compensate for machines that have reversed stereo.

SEE ALSO

     ac97(4), audio(4), intro(4), pci(4)

HISTORY

     The auich device driver appeared in OpenBSD 2.8.

CAVEATS

     Some hardware implementations only support 48kHz sampling rates.
