Noise when playing song

Hi There,

Yesterday i have installed Ubuntu Studio Alternate AMD 64 version.

I have recorded some tracks on my Tascam DP-02CF and want to listen to them and maybe already edit them in Ardour :slight_smile:
But when I play the tracks in Ardour i hear a noise in the tracks.
A sort of static, crackling noise.
When i play the tracks with an other application like audacious everything sounds fine.

Anyone have an idea on this one.

Thanks in advanced,
