The correct way is to provide the real ALSA 's 0dB point (Playback volume) for the user of AC97 sound card so that they can record without any distortion using line in with the loopback cable connected to line out.
Jeez, man, I explained that in my original reply.
If I may quote myself:
'On top of that most volume controls should then mark the ALSA 0dB point as "base" volume on the slider, at what PA then calls -y dB.
That way we will expose 0dB as maximum hw amplitude uniformly on all sound cards and have a special point on the slider that is hinted to be the "comfort" point.
This is all explained on http://pulseaudio.org/wiki/WritingVolumeControlUIs#BaseVolumes'
See? It's all explained there. We still show the ALSA 0dB point on our sliders, we just don't call it "0dB" but "base volume".
