+Subject: [PATCH] HDA-Intel: add Boost volume control for Headset Mic
+
+Ubuntu Linux users complain even they set the input volume to maximum,
+they still can't record sound with a pretty satisfied volume, they
+need to run commandline commands to adjust "Mic Boost/Headset Mic
+Boost/Headphone Mic boost" value to increase the input volume.
+
+That is because the current ucm only defines "Capture Volume" to
+control the input volume. Here we add Boost control, then users could
+adjust both "Capture Volume" and "Boost Volume" through Pulseaudio and
+Gnome.
