Comment(by patra...@gmail.com):
Udev-based configuration of volume limits would indeed work for my use
case. However, it global in the system and is not user-friendly, and thus
some discussion is needed whether it is OK and whether better solutions
exist. Note that the desired limits depend on the sensitivity of
headphones and thus will be different even for users of the same type of
sound cards.
I understand that volume control application and mplayer have the same
rights. Thus, within the solution proposed above, it is indeed impossible
to protect against malice in mplayer (IOW, strictly enforce policy). After
all, a malicious program can access ALSA mixer API directly and thus
defeat the limits even if they are set by udev rules. What I want is
protection against accidents. And I think that a separate API for setting
volume limits (clearly documented as "for use only in mixer applications")
would be enough for this protection.
BTW, if you (or one of your friends) have and a fifth-generation iPod,
please look how the volume limits UI is organized there.
