Yeah but crossfading results in rhythmbox freezing :\. Could be an issue
with GStreamer 1.6. I'll file bugs at a later time.

Well, most of the settings on the ReplayGain plugin really will have<br>

track is having volume reduced the limiter will probably not be<br>

<br>
That said, I just gave it a try... And it looks like there&#39;s a bug when=
<br>
using the non-crossfade backend that some of the ReplayGain settings<br>
aren&#39;t applied correctly. (I tested this with the &quot;pre-amp&quot; s=

which does make audible changes.)<br>
<br>
If you switch the backend to crossfade then everything should work.<br>
Note that the settings appear to only be applied on track change with<br>
the crossfade backend, not realtime.<br>
<br>
Should probably file a bug for this issue...<br>
