Thanks for the reply everyone. I've done some sleuthing through the debug
output, and I believe that I see where Amarok maximizes the volume.
Here's what I did
1. amarok --debug
2. Press spacebar to play the current song on the playlist (volume goes
to 100%)
3. Use the "volume down" key on my laptop a few times to get it down to
58%
4. Pause the song with the spacebar
5. Resume play with the spacebar
6. Exit Amarok
We pick up at #4 in the debug output.

At line 15 play resumes, and I didn't push anything else. Notice how the
volume is changed (lines 39-43). Is there a way that I can see the actual
values in Amarok::MediaPlayer2Player::volumeChanged()? Other ideas on how
to troubleshoot?
Here's some additional info about my system
Qt: 4.8.2
KDE Development Platform: 4.8.5 (4.8.5)
Amarok: 2.6.0
pulseaudio 1.1
Thanks,
Justin
