Volume Control Increase 110% from older versions

[webguru33]

Winamp Version 5.21 I am having to increase the volume to 70% from my previous setting of 33% on older versions. This is to play back all file formats including shoutcast radio stations. All other settings are the same on speakers and wave settings.

P-4 2.8 2 gig mem- Turtle Beach Sound card. (os xp home sp2)
AMD 3.0. Asus Board 1 GIG mem Turtle Beach Sound Card. Same behavior as pentium. (os xp home sp2)
P-4 3.0 Intel Board 1 Gig Mem Onboard: Same Issue
Winamp Version 5.21

NOTE: I did notice this issue with the last version as well. All other prior versions of winamp did not have this issue.
If I roll back to 5.03 I do not get this issue volume is at 33% for play back on winamp.

Amp is off.
