[Rosegarden-user] soft synth, Rosegarden, noises

[Vedran V. <ved...@gm...>]

I have  OpenSuse 10.3. , RoseGarden 1.6.1, Asus laptop, dual CPU T2130
 1.86 Ghz  with 1GB RAM
Soundcard SBx00 Azalia with driver snd-hda-intel
advanced options for sound card 0=auto, 1=none, 2 =posbuf, 3=Fifo size

When I play MIDI file with soft synth played  via DSSl soft synth
plugin , I hear strange noises, a sort of vibrato crackling when notes
are played.

please advise how to remove those noises.  I use FluidSynth3 Sf2 soundfonts.

Thanks,

Vedran
