Headphone has a noisy when shutting down system.

When I shutdown system with 'poweroff' command.
There is a noisy come out from my headphone, the noisy lasts about 1 second....
If I put below line into /etc/modprobe.d/sound.conf

options snd-hda-intel model=,generic

It solves the noisy problem, but at same time, my 'mute status light' on F1 key stop work as well.

So, anybody know how to avoid the noisy when shutting down and keep my status light function works well ?
