ALSA: hda - Fixing background noise on Dell Inspiron 3162

[ Upstream commit 7cb32ae09a6490c27bc3c110ee42d808a5670142 ]

commit 3b43b71f05d3ecd01c4116254666d9492301697d 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.
