When I export my video and play it on my desktop computer the sound is really good. I posted my video to Facebook and viewed it on my desktop computer again it sounds good. When I view it on my mobile phone I can barley hear it and my volume it turned up to max. A friend also said she could hardly hear it on her phone too. Is this a setting that could be causing this when I export? I exported it as a WMV. How can I export my video so the sound it good on all devices?
