If could be useful I have found a workaround for this issue. I hope it is usefull to understand better the problem.
I have an Asus n550JV with ALC668, quad array speaker and subwoofer; I have a dual boot with windows 8.1 and ubuntu14.04 LTS.
If I disable the audio card from windows (by device manager) and restart I have fully working audio on ubuntu.
I write a script which enable and disable audio on windows start and restart event. Please tell me if are useful more alsa or details and log

Now, I'm using openSUSE Tumbleweed and I've no problem :)

Sorry, I can't test your workaround, I'm not using Ubuntu anymore :(
