I also had the same concern as yours yesterday, so i let ShawnWang 
perform the test, he confirmed that adding "model=dell-headset-multi" 
can solve this problem. Below is the irc log:

<hwang4> shawnwang, Does adding "options snd-hda-intel 
model=,dell-headset-multi" solve the problem on this machine (10280640)
<shawnwang> hwang4, yes
<hwang4> shawnwang, ok, got it, i will fix it.

Regards,
Hui.
