The man page says that amixer is for ALSA. I don't pretend to understand
the morass that KDE4 sound is, but my understanding (which could be
completely wrong) is that ALSA has been superceded by Phonon.

Just in case my understanding is wrong, I tried one of the examples from
the man page:

[H:N] amixer -c 1 -- sset Master playback -20dB
amixer: Unable to find simple control 'Master',0
