That's where the 92% came from as the Archos can go up to +12dB (100%). > > In the old Rockbox version, the answer was 92% (if I recall correctly).

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. > Most consumer types would be happier with an inuitive scale.
