For a start, VLC has always disabled the option by default, so there is no understanding of how well this works. Then having more choices than on & off makes little sense to most. And lastly, it won't work when pass-through is negotiated.

Replay gain mode should be available when listening to music. Generally such content don't provide pass-through. There are other options in libVLC that don't work with pass through. I don't get the difference between album or track, maybe we should propose an on-off setting from libVLC ?
