VoodooHDA is an open source audio driver for devices compliant with the Intel High Definition Audio specification. It is intended as a replacement for AppleHDA on Mac OS X with support for a wide range of audio controllers and codecs.
- automatic recognition of all HDA codecs
- test jacks for autoswitch
- control panel for fine tuning
- sound treatment includes stereo enhancements
- since v2.8 it works with two sound cards
Based on the other reviews so far, I guess the code works. But as far as the code goes, it is a hack, not very readable or documented well.
