After adjusting my .config,
I am getting a speaker option to mute
the external speakers, as well as the headphones.
the options that I added were:

SND_HRTIMER [=y]
SND_HDA_RECONFIG [=y]
SND_HDA_INPUT_BEEP [=y]

before adding these, like what I mentioned
there was no "speaker" option(or "front");
As for the sound itself, I'll have to
blast myself with some good tunes,
and see If I hear or experience any anomalies.
(then wakeup the next day unable to hear);
: )
