No sound. Fresh install.

Having trouble with LMMS? Ask about it here.
I have tried ASLA and sdl, but to no avail. I can't seem to get sound to come out. I try to press the bar for test sound that was in the youtube vid. Anyone know what i can do to get it to work.

We need a bit more:
please post your:
* OS (+service-pack-ver)
* lmms vers
* hardware specification (ram & soundcard is the most important)
