Hi and please accept my apologies if this has been posted before but I cannot find any help so far having trawled through acres of internet! I have a galaxy s 3.6 yp-gs1. I can get no media sound out of the internal speaker unless i have the fm radio on! Checking the volume in settings, I get a test tone an all headings apart from media volume, and no sound plays through the speaker on any application.... until I turn the fm radio on to speaker setting. If the radio is on in the background, I get sound through the speaker when playing music or you tube vids but obviously with the radio noise in the background. If I am in you tube I can alter the volume but the volume button is labelled fm radio on the screen. Everything works as it should when the headphones are in.
Has anyone heard of this before and is there a fix ( have reset to factory settings with no success)
