Hey im wondering if this is just mine or what. i plug my headphones in and start listening to music or watching a movie on my phone then i try to use the 5.1 channel and it says "5.1 channel sound effect works in earphone mode only" i have my headphones pushed alll the way in and i can hear the music or video thru the headset but it wont let me go into 5.1 channel any help or ideas on what this problem is will be very much appreciated.
