Comment 15 for bug 1033996

it seem that the problem only occur on those ac97 codecs with headphone volume control since my three sound cards with stac9704, stac9708 and stac9721 still have analog ouput port in pulseaudio

i.e. removing analog output since it is subset of headphone only occur with those on-board ac97 codec with headphone

you have to ask the author of the following patches
