f = Content.Load("Sounds/d");
d was wav file converted to xnb.
Rpg was mp3 converted to 2 files ogg and xnb.
With this code song and soundeffect both sound very diffrent from the original content. Prob both is disorted.
Dont think the real problem here but I am using Content pipeline manually because it creates the files but not showing in project.
My computer is old,using windows 7 and a very old sound card if it may be problem.(Don't have any other sound problems in any game or video in anywhere).
