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
full-duplex operation and has separate channels for line input and microphone.
Unfortunately, simultaneous recording from both line
inputs is not supported due to the current ac97(4) design. Setting
flags to 0x0001 will compensate for machines that have reversed stereo.
ac97(4), audio(4), intro(4), pci(4)
The auich device driver appeared in OpenBSD 2.8.
Some hardware implementations only support 48kHz sampling
