No Sound via headphones

Hi all!
New user of OpenSuse & Linux in general.
I originally used to run Ubuntu on a VM, then tried Mint & Xubuntu... finally OpenSuse & totally loving it.
I've spent a lot of time getting things to work & like how opensuse feels.. and don't want to change.

I am dual booting OpenSuse 13.1 on a late 2012 iMac

I was able to get Sound to work by playing around with the general settings.
However, i've not been able to get sound through the headphone jack.
Have tried multiple earphones & speaker systems..

So, i tried my luck with this thread - https://en.opensuse.org/SDB:Intel-HD...rom_Headphones

These are the contents of my /etc/50-sound.conf


And this is my sound codec

Adding few sound related screenshots
