Hi everybody!
I bought a Terratec Aureon 5.1 PCI which uses a CMI8738-MC6 chip. I want
to play DVDs in 5.1 surround sound.
I already made it do that, but unfortunately the mixer does not give me
the possibility to adjust the volume very detailed, which is an absolute
necessity for my setup (which is a real cinema).
So, I thought I could just add an /etc/asound.conf where I split up the
6-channel signal, apply the softvol plugin to those 6 streams (which
would give me 6 sliders in my mixer) and then mix it all back together
and output it.
As I have never ever done an asound.conf I thought I'd just start with a
simple one by just adding a (more or less dummy) softvol control. So I
wrote the following into my asound.conf:
--------------------------------------
pcm.softvol {
type softvol
slave {
pcm "hw:0,1"
}
control {
name "SoftMaster"
}
}
pcm.dsp0 {
type plug
slave.pcm "softvol"
slave.channels 6
route_policy duplicate
}
pcm.!default {
type plug
slave.pcm "softvol"
slave.channels 6
route_policy duplicate
}
--------------------------------------
I got that snippet from alsa.opensrc.org, specifically for my chipset,
so I thought it should work out of the box.
But unfortunately absolutely nothing happens. In neiter alsamixer nor
amixer do I get a new control called "SoftMaster".
The config file is not being ignored, because when I add some garbage
alsamixer does not start up.
Can somebody please help me?!
