earpiece sound
 

im running DCDs rom 4.1.2 and radio version 3.35.04. the trouble im having is i can noot hear any sound out of the earpiece. ive heard people having this issue with bluetooth and i might have inadvertanly connected to a bt device. since then ive flashed my phone several times trying to resolve this with no luck. today what i noticed was wierd is if i have my phone open (lanscape mode) i have sound. close phone ... no sound. open phone ... sound. is anyone aware of a reg hack or ?? that i could try
thank in advance
