Different volumes in programs using alsa possible?

I want to have different volumes in my programs. For example i want ncmpc to play the music at 40% of maximum volume and mplayer with 90%, but if i change the volume in ncmpc it reduces the volume in mplayer, too. Same the other way. Is there a way to prevent programs using the alsamixer "master" and use their own volume control?

with mplayer you can use softvol option. alsa-lib also has in ALSA_PCM_PLUGINS the sotvol option but I ignore its meaning

thx with mplayer it works now. But is there no general way for this?

check for software mixing... it will use its own mixer relative to your alsa mixer's volume. not all apps support it, ymmv.

cheers

Not directly related, but I think that the phonon engine for kde4 will support this (I am not seeking the kde4 devel too closely). So, you should be able to control the relative volume and other things of all the phonon based programs in an easy way.

Pulseaudio also supports this.
