That is a fairly new motherboard for the seventh generation Intel CPUs?
If yes, then the answer is, no.
You'll need one of the newer kernels. At the moment the most recent "Stable" kernel is 4.13.5 and that will probably change in a day or two.
By the end of this month or the first week of November, the next "Long Term Service" release, 4.14 kernel will be available and it will also support the various chip sets on the newer motherboards.

You can compile your own kernel or Board Member 55050 has been kind enough to provide "ready to use" kernels. They work for me, but YMMV (Your Mileage May Vary).

Edit in: The 4.13.6 version of the latest Stable Kernel was released this morning (12 October 2017).

Hey just messing with ya! LOL

I also have the same chip and I compiled 4.13.5 and it works.

Be sure to compile in;

CONFIG_SND_HDA_CODEC_REALTEK

Try a newer major kernel version i.e 4.13.x . My Realtek 1150 did not work out the box with the kernel shipped with 14.2 I had to compile 4.10 at the time to get it to work, but it now works with the patched 4.4 kernel included in the 14.2 patch updates.

I just said all this, look up at my reply and URL, there's no guessing here, the URL is a report on when the support was introduced...

So now that means the only update to date, latest kernel to use at this moment is 4.13.5, if you want the latest stable...
