HDA Intel PCH ALC1150 No Sound Ubuntu 14.04x64

Question

I have a new machine running a Gigabyte Z170N-Gaming 5 motherboard with an HDA Intel PCH ALC1150 sound card. The sound card produces a slight hiss, but I receive no output from the analog line-out. Muting the card actually mutes the hiss, so I have to believe I'm controlling the correct device.

I've followed other suggestions by adding the following to the end of my /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=pch position_fix=1
options snd-hda-intel single_cmd=1
options snd-hda-intel probe_mask=1
options snd-hda-intel model=basic

and I've put the following into my ~/.asoundrc (I don't even know if this applies to Ubuntu):

pcm.!default {
    type hw
    card PCH
}

ctl.!default {
    type hw
    card PCH
}

I've reinstalled pulseaudio, run through alsamixer playing with levels, built the latest alsa-lib from the alsa project, and pretty well exhausted every option I can find.

I even purchased a Turtle Beach Amigo II USB sound card, but that has terrible audio out.

Is there anything left to try?

Try sudo apt-get install --install-recommends linux-generic-lts-wily — QwertyChouskie, Mar 21 '16 at 14:39
Never mind that. I was able to find that answer here among other places. Giving the kernel upgrade a go... — Jerbot, Mar 21 '16 at 17:20
Bingo. Throw your comment up as an answer and I'll award the bounty. A little explanation for why this works would help future folks too. — Jerbot, Mar 21 '16 at 17:37

Run:

sudo apt-get install --install-recommends linux-generic-lts-wily

This will install the new kernel version from Ubuntu 15.10. For details, see: https://wiki.ubuntu.com/Kernel/LTSEnablementStack
