My motherboard is Asus M4N68-T-M V2 with VIA HD Audio as the sound.
The problem: I'm using a headphone but when it is plugged it, both windows7 and via hd audio deck recognize the device only as a Speaker instead of Headphone. I've tried uninstalling sound driver as well as VIA HD audio deck but still it doesn't work.
If I set Headphones as the default device, there's no sound. There is sound on my headphone as long Speaker mode is set as default device instead.
Btw my headphone is plugged at the back, when I plug it in the front it doesn't work presumably the jack at the front has spoilt but this didn't quite matter since I was using the back jack in the past with no problem and the mode used to be Headphones but now it's Speaker mode. I've also tried inserting in my iphone's earphone instead and it is still Speaker mode

Hope you guys can help me out!
