[Solved] Boost volume beyond ALSA limits

The volume going into my speakers with Master and PCM maxed is quite powerful, and totally great.
Sadly, when using earphones with my speakers, it is definitely not.

My speakers are the type without a volume control.
Without buying additional hardware, is there any way I can force ALSA to go to higher volumes?
Yes, I know, that can induce crackling, etc... I don't really care, I just need more volume, from the entire system (not any one app).
Like I said, I have Master and PCM maxed.

Thanks very much for any tips!

IIRC PulseAudio can do that, ALSA can't. You can use some software (sox?) to make the music louder before sending it to your headphones.

Dang, I was really hoping there was some way this could be done without Pulse.
Thanks though.

It might be possible with the ALSA softvol plugin's max_dB parameter.

Thanks Leffe!
That was exactly what I was looking for.
Some problems because of going that route, but it's far better than nothing.
