There are many threads on the internet regarding the Realtek ALC1150 driver and alsa, with most ending up buying some other soundcard. 
I’m running 13.1 64bit on intel iron, specifically the supermicro X10SAE. I have successfully run the Realtek 5.18 driver tarball, well presuming successful means it looks like the driver was installed. [Some would say success means it actually works.]
Regarding the Realtek driver, here are the tricks to get the installation to run to completion. First, the driver is found here:
http://www.realtek.com.tw/downloads/
Go to high definition audio codecs, then pick the driver for linux driver 3.0 .
The installation is the usual ./configure make make install. However the make will crash due to an error explained here:
http://stackoverflow.com/questions/19672884/error-when-building-wifi-drivers-on-ubuntu-13-10
The webpage is for an error with the wifi driver, but it is the same basic error. The make will indicate the line with the error. Just edit the text as explained on the webpage and the make will work. The driver installation requires the linux kernel source to be installed.
Since I can’t get the official Realtek driver to work, the alsa-users list suggested I reinstall the desktop kernel. Fortunately there is a thread on the opensuse forum specific to doing this, and the only successful thread I found on using the ALC1150 chip.

However modprobe snd-hda-intel just locks up the terminal window until I control C out of it.
Since it is easy to reinstall the Realtek driver with a “make install”, I did that. The results are the same. The modprobe command just hangs.
I ran the yast2 hardware sniffer with these results regarding sound:

Driver Info #0:
Driver Status: snd_hda_intel is active
Driver Activation Cmd: "modprobe snd_hda_intel"
Config Status: cfg=yes, avail=yes, need=no, active=unknown
Note that the opensuse thread I referenced has dashes in snd-hda-intel rather than snd_hda_intel as shown in the hardware probe. However modprobe snd_intel_hda still locks.
If I go to yast2 then sound, it indicates the drive is indeed snd-hda-intel. Atempting to run alsamixer yields “cannot open mixer: No such file or directory”
If I go into yast2 then sound and delete the sound card then try to add one, I do find snd-hda-intel, but there are a number of choices for drivers. Since the X10SAE has 7 channel sound, I assume I need ICH7. Trying to add that soundcard (ICH7) then going to quick installation just locks up the sound installation so badly that only booting kills the process. I tried using kill -9 with no luck.
I’m not completely sure the sound installtion is finding the new realtek driver or the default kernel driver. Nothing in the sound installtion indicated Realtek.
