Comment 4 for bug 807944

However, I just noticed that when I turn off the ReplayGain plugin in Rhythmbox, the FLAC file sounds louder, too. So with the enabled plugin Rhythmbox seems to reduce the volume of every file - whether they have a replaygain tag or not.

Now I am confused. Two questions come to mind:
1) Isn't it possible just to read out the gain tag of FLAC files like the metaflac command and apply the volume when playing? (Is there actually a player which can do that?)
2) If the answer to question no. 1 is no and there will be no way to do this in Banshee... is there a similar "ReplayGain" plugin (as there is in Rhythmbox) for Banshee which just normalises all songs to an average volume when playing?
