Yesteday the forum helped me with my sound when doing video, my General settings were already set correctly. I found a youtube video that shows you how to pull the cache for sound and it works great now. I'm attaching the link to the video, its a bit out of focus but it does show the steps on what app is needed to pull the video cache using ifunbox.
