NetBSD thoth.private.sigusr1.org 1.6.1 NetBSD 1.6.1 (THOTH) #8: Sun Jun 22 20:27:17 PDT 2003n root@thoth.private.sigusr1.org:/usr/src/sys/arch/i386/compile/THOTH i386

>Description:
i82801EB (ICH5) AC-97 Audio is not supported as an audio device under NetBSD 1.6.1.  The ICH5 is normally seen on motherboards based around the i875P chipset.

According to Intel it is fully backward compatible with earlier ICH AC-97 controllers.
>How-To-Repeat:
Install NetBSD on a computer with ICH5 onboard audio.  auich will fail to detect the device.
>Fix:
The following patch adds basic support for the ICH5.  Tested on Asus P4C800 board by mp3 playback via xmms.  (Need to regenerate pcidevs.h before build).

Known Issues: None of the features unique to the ICH5 are supported, and on my system audio is being outputed from the line in jack.
