I just watched a movie and had to set the volume level quite high to get audio. I forgot to set the volume to the lower level it was at and started a trance music track and that literally made my ears hurt a lot because I'm wearing closed headphones!

Is there a way to limit the output volume level (dB) at some sensible level regardless of the volume applications output?

UPDATE: this might not be possible (see answers below and on David's link). In any case no one here knows how to do it. But if you get it working, please let me know!

It would be cool if you could have application-specific presets. It might be possible, I'm not sure. – FrustratedWithFormsDesigner Aug 10 '10 at 20:26

@David: it's a duplicate, apparently. – Albert Peschar Aug 13 '10 at 20:32

For movies with low volume I always prefer to over-amplify from mplayer (check --soft-vol option, or something similar) than to rise the system-wide sound volume. For music and other stuff you usually don't need to change the volume.

This does help me a little. Thanks! – Albert Peschar Aug 13 '10 at 20:34

PulseAudio could help you. It lets you use volume levels on a per applications basis.

Oh yea, forgot about that – TheLQ Aug 11 '10 at 1:58
It's a shame though that PulsaAudio uses about 4% CPU on my Core2Duo. Sorry but I think this is an unacceptable amount of processing power for just having PulseAudio staying in memory. The usage obviously goes up when you actually listen to something. – Patkos Csaba Aug 14 '10 at 13:15
