Sound keeps changing in Fedora18

[Mickey]

The sound keeps changing in Fedora 18/ KDE.
I go into Pavcontrol and Alsa is set to 100% in Playback, I have to move 
it up to 150% to hear sound at a proper level.

The Mixer controls are set to max but you can barely hear audio.

If I play a song off Hard drive it is to loud, and I open Mixer and 
reduce audio to a comfort level and then move it back to max output and 
the sound level does not go back up.
