Openshot Video/Audio Preview has no Sound

Im trying to edit some videos in Openshot but there's no sound in the preview window. Sound works when I play the videos on VLC however.

The videos play with melt but they also have no sound. Im running Ubuntu 12.10. Spent a good two hours on Google searching for a solution with no results yet.

I had same problem on version 2.5.1, Worked for about 2 hours changing audio settings on pc and then matching those settings to OpenShot. Nothing helped.The solve for me was,in OpenShot go to Edit-Preferences,(Tab) Preview, Playback Audio Device (changed to DirectSound;Speakers.Found this trying each setting as 3 different settings seemed to be the same ,however only the one worked.

Right click on the video in 'tracks', go to properties, and make sure 'enable audio' is checked.

Audio (sound) has to be enabled on your track (ie: video) for you to be able to hear anything when you play your preview or download your video. When I first installed openshot I had the same problem as the OP- enabling audio solved it.

Openshot requires a video stream and an audio stream and you have to make sure that the eye and speaker icons are present and active to view and hear the video and that audio levels are normal...
