ALSA Pre-Amp not showing up in alsamixer

I'm trying to add a pre-amp to alsamixer as per these instructions. My /etc/asound.conf is as follows:

pcm.!default {
  type hw
  card 0
}
ctl.!default {
  type hw
  card 0
}
pcm.!default {
  type hw
  slave.pcm "softvol"
}
pcm.softvol {
  type softvol
  slave {
    pcm "dmix"
  }
  control {
    name "Pre-Amp"
    card 0
  }
  min_dB -5.0
  max_dB 20.0
  resolution 6
}

The control isn't showing up in alsamixer. alsamixer is showing the proper card, Intel HDA, which is set to card 0. Any idea what the problem is? I've tried both plug and hw as type. Much thanks.

Re: ALSA Pre-Amp not showing up in alsamixer

You are overriding the default control device back to the non softvol control. Replace your file with

 pcm.!default {
    type plug
    slave.pcm "softvol"
    hint {
           show on
           description "Default device"
     }
}

pcm.softvol {
    type softvol
    slave {
        pcm "dmix"
    }
    control {
        name "Pre-Amp"
        card 0
    }
}

Retry, also post

aplay -lL
amixer

Preferably in [ code ] tags, not [ quote ] tags.
