I would like to share that I found this post referring to a similar
issue where sound settings weren't maintained, maintained being a better
word than saved because I believe alsamixer might properly save the
settings.

According to the post it is pulseaudio which is actually modifying the
settings:

http://askubuntu.com/a/549939

I tested as suggested, by modifying the "Headphone Mic Boost" within
alsamixer and exiting.  I then ran:

pulseaudio -k

And pulseaudio reset the "Headphone Mic Boost" to dB gain 0.00, 0.00.
The hissing reappeared.

If I could get pulseaudio to stop resetting the "Headphone Mic Boost" in
alsamixer, then that would be an acceptable workaround.

But, I think the real issue still needs to be resolved.  One would
expect a dB gain 0.00, 0.00 to be absolutely silent.  The user should
not need to kick it up a notch to dB gain 10.00, 10.00.
