create /etc/asound.conf
and paste this:
Quote:

pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "softvol"
}
pcm.softvol {
type softvol
slave {
pcm "dmix"
}
control {
name "Pre-Amp"
card 0
}
min_dB -30.0
max_dB 30.0
resolution 6
}


You have to restart the computer to see any effect.
Then you get PreAmp in retrovol

I thought "Line boost" and "Mike boost" were pre-amps, in effect.

I tested it in precise, so not sure about others.

Yes the PreAmp really does boost the sound past all the other mixers, but the louder you go the more distortion you get so its a trade off.

For some reason, I had to reboot several times to get the preamp to show up in Retrovol.
Several different Puppies I have used this in.

What about if you already have an existing asound.conf in /etc.....with totally different contents?

Do you simply add this underneath, or what?
