Can you be more specific about "unable to manipulate the sound volume
at some point"?

fade is not (yet) supported by VLC phonon backend for Amarok.  VLC is
simply lacking the implementation for the feature.  See here:
https://bugs.kde.org/show_bug.cgi?id=287124

Since fade is not supported by the VLC phonon backend, it's
recommended to disable fade-out in Amarok when you use the VLC phonon
backend.

For ReplayGain, can you make sure you don't have conflicting gain
tags?  Check if your files have a replaygain_track_peak tag, and if
so, remove it.

As far as I know, Amarok itself does not calculate ReplayGain values,
you need to have a 3rd party app calculate it and store the
information in a ID3 tag.

I have just tested using mp3gain from Wheezy with the Amarok from
Wheezy and the ReplayGain feature in Amarok works fine for me here
with both the gstreamer and vlc backends.  Of course, I made sure
ReplayGain was enabled in Amarok in the menu.  If you've used older
mp3gain versions, it's very possible you could end up with conflicting
ReplayGain tags which is known to cause problems as Amarok doesn't
know which tag to use and may decide to use the wrong one (or
neither). Also, if you use a very old version of mp3gain, the tag
might get ignored by Amarok completely.

Hope this helps.
