HP Laptop Headphone Fix

Love my HP Pavilion DV6 laptop, and love Ubuntu running on it, but found an issue with my headphone, that plugging into the jack didn't turn off the speakers.  Did some poking around, and found that adding:

options snd-hda-intel model=hp-dv5

to my /etc/modprobe.d/alsa-base.conf took care of it.  There are other values for model that can solve issues with other machines.  For reference, lspci reports:

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)

for my audio card, and cat /proc/asound/card0/codec* | grep Codec reports:

Codec: IDT 92HD75B3X5
Codec: Intel IbexPeak HDMI

for my codec(s).
