[SDL] [SDL_mixer] artificial background noices

[apator10 at wp.pl]

hi again

music playback sounds noisy
for every type I checked ( .mod, .xm, .ogg, .mp3, .mid )
even if I set CD quality parameters

first I thought that was getting 8 bit format set, or 11KHz freq
so I checked with Mix_QuerySpec();
and I got:
44,1KHz freq ( as requested )
AUDIO_S16SYS ( as requested )
2 channels ( as requested )

next I thought that I was using some down sampled music
( those artificial background noices sounds like it was the case )
but no, I play tested everyone of them using other players
and everything sounds fine

so does enybody know why music is so noisy?
any suggestions?
