Hi Jei,
Thanks for replying back,
I have put the video in a zip folder as the website does not allow me to upload mp4 files. The problem does not occur in a specifc app. The problem is that there is a delay between plugging in the headphones and it registering as being "plugged in". I currently use skullcandy jib wired earbuds, but this problem occurs no matter what headphones I use. This does indeed happen every time I plug headphones in.
