Asus g73jw - Subwoofer disabled in alsa-Still hear sound(no lowpass)

There are three internal speakers.  Two are front speakers and the third is a subwoofer.  The subwoofer should be playing lowpass audio only.  In alsamixer, the subwoofer is muted and cannot be unmuted.  However, when playing audio, sound is passed through the subwoofer (sound that is being played in front speaker).  This leads to weird/unbalanced audio. I've looked through and played with different .asoundrc but nothing seems to help. I wrote down the basic information below.  Please let me know if further information is required. 


https://bbs.archlinux.org/viewtopic.php?id=119710  This thread looked promising but I can't decipher the solution so I have not tried it.  Any other comments, ideas, and brainstorming are welcome.
