It's really strange.  Are you sure that this is the kernel you
modified properly?  Before further debugging, check two things:

- Run "git log sound/pci/hda/patch_realtek.c" and the first few
  entries, whether they come from sound git tree.  For example,
  check the commit below is contained:

  commit 7ec9c6ccc6007b14a916021d4ba7ffbcc7822ae3

    ALSA: hda - Fix volume-init for ALC259 with invalid widget caps
- Confirm the running kernel is what you really built and installed.
  You can modify the suffix via $CONFIG_LOCALVERSION in .config file.
  Name it uniquely, rebuild, re-install and reboot.  The new suffix
  should appear in the output of "uname -r".

- Once when these are correct, check /proc/asound/card0/codec#0:
  the widget NID 0x02 should contain "Speaker Playback Volume" instead
  of "Headphone Playback Volume" with the latest driver.
