[LAU] LinuxSampler output distorted

Hi all, I have been trying to switch my live performance laptop from using specimen to LinuxSampler because it has quite a bit more features and such, but I can get LinuxSampler to work correctly. All the audio output is distorted in a bad way and kind of varies, some samples i can make out but are garbled or crackly, while some sqeel and other sare just static. I have tried my setup on two different laptops, one running 64studio 2.1 with a Cirrus Logic Sound Fusion CS46XX and another running UbuntuStudio 8.04 with an internal intel-hda card. I also tried both my usb audio devices, a M-Audio Ozone and an Edirol UA-4fx, through jack on both laptops. I also tried upgrading from the stable ALSA which i belive was 1.0.13 for etch to the backport 1.0.17. I also tried turning down levels in alsa mixer, my gig instrument, my sampler channel and the sampler master. I then proceeded to build LinuxSampler from source and tried that. All off these attempts gave me the same distorted result coming out of my speakers. Does anyone know why this is happening or have an idea to try? Thanks, Brian
