-* Channel Mode
+Channel Mode
   This is an enum control to change the surround-channel setup,
   appears only when the surround channels are available.
   It gives the number of channels to be used, "2ch", "4ch", "6ch",
   and "8ch".  According to the configuration, this also controls the
   jack-retasking of multi-I/O jacks.
 
-* Auto-Mute Mode
+Auto-Mute Mode
   This is an enum control to change the auto-mute behavior of the
   headphone and line-out jacks.  If built-in speakers and headphone
   and/or line-out jacks are available on a machine, this controls

-* Analog Loopback
+Analog Loopback
   This control enables/disables the analog-loopback circuit.  This
   appears only when "loopback" is set to true in a codec hint
   (see HD-Audio.txt).  Note that on some codecs the analog-loopback
   and the normal PCM playback are exclusive, i.e. when this is on, you
   won't hear any PCM stream.
 
-* Swap Center/LFE
+Swap Center/LFE
   Swaps the center and LFE channel order.  Normally, the left
   corresponds to the center and the right to the LFE.  When this is
   ON, the left to the LFE and the right to the center.
 
-* Headphone as Line Out
+Headphone as Line Out
   When this control is ON, treat the headphone jacks as line-out
   jacks.  That is, the headphone won't auto-mute the other line-outs,
   and no HP-amp is set to the pins.
 
-* Mic Jack Mode, Line Jack Mode, etc
+Mic Jack Mode, Line Jack Mode, etc
   These enum controls the direction and the bias of the input jack
   pins.  Depending on the jack type, it can set as "Mic In" and "Line 
   In", for determining the input bias, or it can be set to "Line Out"

-* Smart 5.1
+Smart 5.1
   An enum control to re-task the multi-I/O jacks for surround outputs.
   When it's ON, the corresponding input jacks (usually a line-in and a
   mic-in) are switched as the surround and the CLFE output jacks.
 
-* Independent HP
+Independent HP
   When this enum control is enabled, the headphone output is routed
   from an individual stream (the third PCM such as hw:0,2) instead of
   the primary stream.  In the case the headphone DAC is shared with a
   side or a CLFE-channel DAC, the DAC is switched to the headphone
   automatically.

+Loopback Mixing
   An enum control to determine whether the analog-loopback route is
