I have a fresh install of KUbuntu 14.10 with this problem and i come of a KUbuntu 13.10 without problems.
I don't have any sound from speakers or headphone, i think the driver isn't loaded, but the microphone works, it records. The sound playback works too, but the sound doesn't go through speakers or headphones.
I was testing with a lot of LiveCD KUbuntu when the problem comes. With LiveCDs KUbuntu 12.04.5 LTS, 12.10, 13.04 the sound works, they configs the sound system as "HDA Intel AD198x". Since LiveCDs 13.10, 14.04.1 LTS and, of course, 14.10 Live CD and my install, i have this problem, because the sound system is now "AD1986A". I will attach the alsa-info output for all this systems in my computer.
But with HDA_Analyzer http://www.alsa-project.org/main/index.php/HDA_Analyzer i found the details of the problem: i can create a python script to bring back the sound working in a basic mode, like as previously. The details are activating EAPD in Card 0, Codec 0, Node 0x1b PIN (In my computer, it could be different in another) what bring back the sound to the speakers, and unmuting "Output Amplifier" in Card 0, Codec 0, Node 0x1a VAL[0] and VAL[1] to bring back sound to the headphones when they are plugged. I will attach too the output of this diff and the python script created by HDA_Analyzer for my system.
At least, the basic working state should be back, because with a untoching fresh install there isn't any sound. There are related bugs here and other post in internet, but i collected all information i found and can give more if it's necessary.
For additional information: Searching the solution, i tested too all the models availables for HDA Intel AD1986A (editing /etc/modprobe.d/alsa-base.conf with AD1986A models /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz) and i found the default one don't fits my system and anothers are better, but have problems of no sound too and i don't found how to fix these problem. When this bug is corrected, i want to help to found a better model for my computer, i don't know how now, but first it bring back the sound. Also, i test with snd-hda-tools https://launchpad.net/~diwic/+archive/ubuntu/hda and with hda-jack-sense-test the Green Line Out sense don't works (always NO present) but the Pink Mic works without problems.
