Volume Resets at Pause

Tue Aug 28 06:08:25 UTC 2012

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
