[gentoo-user] how to change volume when using dmix?

[Volker Armin Hemmann]

Hi,
I am using the alsa-dmix plugin since ages and have and had always  the same 
problem:

in alsamixer/kmix/kamix etc, I am not able to influence the (pcm) volume 
anymore.

Sure, I can chnge the 'master' but this does not help much, when civclient is 
damaging my ears, and I would like to listen to line-in. 

So, is there a way, to change the dmix-volume?

Sure, xine does it, but again, this does not help me with civclient, for 
example.

This is the current .asoundrc, from the gentoo-wiki, but I tried a lot of 
different ones, without success.

pcm.dmixer {
    type dmix
    ipc_key 1024
    slave {
        pcm "hw:0,0"
        period_time 0
        period_size 1024
        buffer_size 8192
   rate 44100
    }
    bindings {
        0 0
        1 1
    }
}

pcm.dsp0 {
    type plug
    slave.pcm "dmixer"
}

pcm.!default {
        type plug
        slave.pcm "dmixer"
}

pcm.default {
   type plug
   slave.pcm "dmixer"
}

ctl.mixer0 {
    type hw
    card 0
}

Glück Auf
Volker
