There may be an option to turn this feature off, I'm just too lazy to figure it out.
I just checked, and you're right! Except, my volume only goes down a tiny bit (maybe 1/10 of the full scale).

This is with the Advanced Power applet.

I'm not disputing your (or anyone else's) word. Just how it works here.

Perhaps there is more to do than just installing Advanced Backlight and enabling it (and disabling the Nokia one, of course)?
You're right; current behavior verified here, but I think I was remembering the behavior correctly, indicating Nokia changed where that policy is implemented.

I think it may be related to multimediad, which showed up at or around Diablo and enforces Nokia sound policy all over top of some (previously possible) BT/alsa tweaks. (In Chinook, for example, I could listen on BT, external jack, and internal speakers siumultaneously.) Unfortunately, that seems to be closed source, so some effort would be involved in figuring this out. With both sets of earbuds I use, or wired speakers, I never need the volume above ~50%, so I didn't notice. (I do crank the internal speakers to 100% and jack up the DMA 4 notches when cycling with no phones, but that's unaffected.)

What would be nice is a flexible, configurable variant of multimedia, which lets the local administrator (i.e. me) control policy, so I could have multiple profiles defined; one could go full volume with speakers, 40% with phones, another would leave phones alone, but mute (instead of switching to speakers) if they come unplugged, and so on. But it seems the policy is implemented in code, not config, and the code is closed. I guess forcing your weird sound policy down users' throats is what's known as a value-adding differentiator...

There's no any mode to up more the master volume? In my n800 the volume even with max in system and in player is not too loud... not exist some way to modify this???

Well... I don't like recommending this method all over the forums, since it is advanced, but as I haven't found a simpler way:

Install Easy Debian Chroot; this lets you have a Debian system on your SD card and run programs from it inside Diablo.

Use Debian's gnome-alsamixer, alsamixer, or any other ALSA mixer program (needn't be from Debian, but AFAIK one doesn't exist for Maemo) to adjust the DMA control up maybe 4 notches.

Easier options (depending on what you're trying to play, and how you're playing it) might include losslessly amping your mp3s with mp3gain or configuring mplayer with softvolume, but the DMA tweak works for all sounds.

All sounds naturally including those from movies, games, etc.
