Nexus Media importer : No sound when playing playback or uploading to YouTube, Facebook, etc.

Hi Guys/Girls

I am having problem with my nexus 7 and nexus video importer. The Problem is I use to upload videos from my action cam (SJ4000) to nexus 7 then social media. Now when I upload video from my action cam, It uploads without sound. I use Diceplayer to view on devices but can't upload video with sound anywhere?
Any advice?
Thanks
