As for your problem, on your Windows Taskbar, on the lower right, you will see a little speaker icon.
Right mouse click on it and you will see Volume Mixer. Make sure Pinnacle is there with the volume all the way up.
Also, in Pinnacle on the lower left, you will see the VU meters. When you play back your clip, do they move?
Also, if you load the Sample Movie (?>Load Sample Movie), does it have sound?
