This is a follow up question for anyone.

This boils down to a general question about new kernel compilation.

To try and solve my no sound issue, I waited until 3.14-rc3 kernel went live.

In the 3.14-rc3 kernel source folder, this patch is located at:
sound/pci/hda/patch_realtek.c

I thought that simply compiling the latest kernel, and then installing it,
would apply all relevant patches (more than the realtek patch may be in
play), but now I'm not so sure.

The question is this: Does a 3.14-rc3 compiled kernel already include the
above patch? Or, because it is labeled as a "patch" within the source, do I
have to actually patch the source before compiling?

IOW, does the patch get compiled, or does anything labeled as a patch within
the source still have to be manually patched against the kernel?

Thanks to anyone who can answer this.  I complied and installed the 3.14-rc3
kernel without a problem. It was the default kernel in grub. But I'm still
dealing with the exact same no sound issue as if booting into 3.12.
