Player changes wave-level in mixer
 

I don't know if it's actually a bug, maybe I'm just too stupid to configure the preferences...

Every time when I play a movie (with mpeg layer 3 sound), the wave-volume in the windows soundmixer goes half way down (and stays there until I change it manually). Playing the same movie with wmp10 has no effest on the mixer-settings.

I have WinXP PRO with SP2 and wmp10 (just installed wmp10 new XP, so I can't say if the problem occured with previous version of wmp)

Any Idea what to do?

Do this in the Settings for BSPlayer:

Go in under "Sound" -> "Equalizer" and uncheck "Equalizer enabled".
If that doesn't solve it, try deleting your "BSPlayer.xml" and "BSPlayer.[Name].xml".
That should solve it.
