if you are using loadSound() command it will cause that effect as OGG files are encrypted the solution is
LoadSoundOGG
LoadSoundOGG( iID, sFilename )
integer LoadSoundOGG( sFilename )
Description
Loads a sound file from the application media folder. File paths must be relative, not absolute, you cannot load sound files from elsewhere on the disk.
This command takes a compressed OGG file and decompresses it during loading, allowing you to save file size, but memory usage will be the same as
if you used a WAV file. If you want to use OGG whilst also saving memory then use the new LoadMusicOGG commands.
