(Get the code!)
HDA sound cards are based on a combination of many chipsets and audio codecs. Many of them don't have hardware mixer controls, or there is no documentation on how to use them.
Alsa in the snd-hda-driver has a big list of quirks that enable specific controls for many chipset/codec combinations, but not all of them.
Newer versions of alsa have more support for these combinations. The problem in Kmilo perhaps is that you can choose an arbitrary mixer channel to control, and the mechanism to get that channel from kmix seems to be broken.
I hope that this clarify the situation about this bug report.
I haven't tested the current hardy situation with kmilo 3.5.9, so I can't say if they have fixed the problem or not.
