Another problem I've encountered:
I've got one mp3 (as for now I've found one) which when playing has a strange background metallic noise. It happens only when I'm using BASS_DEVICE_FLOATDSP in BASS_Init.
I set the volume after having loaded the song with BASS-StreamCreateFile, but it doesn't help. But when I pause the song and unpause it it plays properly.
What is wrong?
