Hi! I have an xps420 dell, I have the front sound and microphone jacks and the back ones like normal. Last night my headphones snapped off the metal part at the end inside the front jack and its lodged inside. So I thought NO biggy ill just use the back jacks from now on. Well the problem lies now the computer wont play ANY sound even with the back jacks. Im assumeing thats because maybe its still reading that front jack as something it can output sound through. So my question is how can i DISABLE the front jack and bypass it to the back sound jacks so that i can get sound back. Or maybe if anyone else has any ideas as to why the sounds not working anymore would be nice to. Thank you!
