That's where the 92% came from as the Archos can go up to +12dB (100%).

I don't think this is intuitive at all if it is not clear that 100%
refers to 0dB. And you'll get other problems. You can allow values
larger than 100% for players that have more headroom, fine. What about
the lower end of the dynamic range? Where are the 0% for players with
different dynamic ranges? Do you allow some player to go down to 30%
only and others down to -10% or would you prefer a nonlinear scale where
0% is the minimum level of the specific hardware? If you choose the
latter, 100% will be the only value for which the volume is the same for
two models. In this case, headphones which sound fine at 70% on one
model will sound completely different at 70% on a different player
model.

Perhaps it's enough to add "dB" on the display to make it clear?
