Duplicate Stereo Signal to Other Outputs with ALC1150

[Google Sucks <dextor41@xxxxxxxxx>]

Dear Mailing List Members,

I would like to configure my audio output to be stereo, but in addition, to send the stereo signal not only to the Line Out (Front L/R) jack but also to the Line In jack. Reason being that I have headphones connected to Line Out and speakers connected to Line In. I am using Line In for speakers because on Windows, in the RealTek control panel, only Line In and Mic In can be re-assigned as Front Speakers Out when using Stereo setup.

I would like to use the setup as I described it as a default Pulse output as well as a selectable ALSA output for ALSA enabled apps (like Doom3 and DeadBeef).

I am a newbie to Linux, used to doing everything using my mouse in Windows, so kindly please provide the most exhaustive instructions possible.

I am using KDE Fedora 20. These are my outputs of aplay -l and aplay -L:
