It might be worth trying again with the latest v1.16 which had fixes for video on some devices - other than that, I'm not sure. I've had some reports of problems on platforms like Omnirom and Cyanogenmod which I haven't got to the bottom of yet (unfortunately no way for me to currently test/debug these platforms).

Another thing to try might be Settings/Photo and video settings.../Audio source, just in case switching that helps.
