Audacity volume

[glowplug]

Despite following SilverDNA's post here (about 2/3 down page), my music files play about half the output volume as Oblivion's once in game.
That is, export from Audacity using...
Bitrate: 192 kBits/s
Channels: 2 (Stereo)
Sampling: 44 kHz

If I load an Oblivion file such as Data\Music\Explore\atmosphere_01.mp3 then export it with same settings there is no problem.

Is anyone getting clues on what may be going wrong here?

The reason I went in search of that post in the first place was how silent the voice files in Nagasteim played back.
That is a worry, as if SilverDNA's voice settings don't work either I have a real problem for my next mod.
