The user needs to configure this as part of their system integration. There's no real way to know what configuration is sane for a given machine and the user is already doing system integration anyway; putting things into userspace makes things much easier to maintain. Even for something like this we'd need to know if the output is connected to headphone or line outputs as the volumes configured would generally be rather different (and of course that can vary at runtime...).
