[Impact]

 * The internal mic default volume is too low
   A upstream commit correct the init configuration

[Test Case]

 * Using gnome-sound-recoder to record audio without tweak capture volume
   The volume is very low
 * Try to update the init.conf mentioned by
   https://github.com/alsa-project/alsa-ucm-conf/commit/263bd26b1216c933db3d216197a78678d0f8610e
   $ alsactl init
   $ amixer cget name='rt715 ADC 07 Capture Volume'
   numid=14,iface=MIXER,name='rt715 ADC 07 Capture Volume'
  ; type=INTEGER,access=rw---R--,values=2,min=0,max=63,step=0
  : values=58,58
  | dBscale-min=-17.25dB,step=0.75dB,mute=0

 * Using gnome-sound-recorder to record again
   The volume is significantly improved
[Where problems could occur]

 * The change only apply to the hardware with rt715 codec.

 * The change adjust the volume only, but not change other control,
   the worst case is the change doesn't take effect.

[Other Info]

 * The change has been verified on Latitude 9510.
