Setting limit volume on rockbox?
Llorean:
Frankly, a maximum volume limit won't stop an uncareful user. If it doesn't get loud enough, they'll look for something to disable so that they can get it louder.
I understand trying to limit it to prevent accidents, but if you teach someone to be careful about their hearing, and they consciously choose to disregard you, as long as the option's there there's a good chance they'll find it.
I still don't understand, what exactly is the problem with using Precut? And if you haven't established a problem with precut, why are we continuing this conversation at all, since it does everything you've asked so far?
safetydan:
@Kay, that particular bug of the precut setting wrapping around should be fixed in the latest builds.

That answers one of my concerns. The user I have in mind wouldn't go into advanced settings to defeat the volume limiting range, but *would* possibly set the top volume higher than it should be - say, a 10 year old. Perhaps they're too young for some players.
I remember Sony had a volume limiting range (maybe European models) that savvy users soon discovered how to defeat. Fine, they should be able to...but a parent might not want to do that for their child's system.

I believe the solution lies outside of Rockbox, as the sound pressure level experienced by a user will be a combination of the electrical gain (controlled by the firmware) and the sensitivity of the headphones being used.
Acoustic shock prevention in telephone systems is partially controlled by network gain plans, but increasingly through the use of headsets which have built in protection. (Google 'acoustic shock' for more on this)
I'm not aware of any headphones for music players which claim to have 'protection' , but a simple solution might be to use some less efficient headphones than the standard ones. This will limit levels with Rockbox or the OF, but obviously it doesn't take much to plug in a more efficient set of headphones if someone wanted to bypass the 'protection'.
safetydan:
So what concerns do you have remaining? The precut will limit the volume in the way you desire. It's a setting buried sufficiently far down the menu hierachy that you won't accidentally undo it. And it now won't wrap.
