Have you tried installing using Synaptic? Open Synaptic and type alsamixer or gnome-alsamixer into it and you should see it there. I only just found and installed it a few minutes ago 'coz I couldn't get enough volume out of this box. Once Synaptic does its magic you'll be able to find it in the menu Applications >Sound and Video

(I'm running 8.10, and I'm a complete Ubuntu/Linux noob of three weeks standing, so haven't yet looked at other versions to see if above method works in earlier distros)

This worked for me:

create a ~/.asoundrc file in your home directory such as this one:

pcm.loudmic {
type asym
capture.pcm {
type softvol
slave.pcm "hw:0,0"
control {
name "Mic Boost"
card 0
}
max_dB 20.0
}
}

You will get a shiny new "Mic Boost" control in the mixer preferences, and if
you select "loudmic" as your input source in Skype, the sound will be
accordingly amplified.. And check the threads on launchpad for other fun tricks

ALSA and Pulse are buggy buggy... please someone acknowledge that ALSA and
PulseAudio have too many _severe_ bugs :) And please let us know how we can
help the ALSA and Pulse teams to fix all these problems :) Thank you
