ALSA: hda - Fixing background noise on Dell Inspiron 3162

commit 3b43b71f upstream.

After login to the desktop on Dell Inspiron 3162,
there's a very loud background noise comes from the builtin speaker.
The noise does not go away even if the speaker is muted.

The noise disappears after using the aamix fixup.
