No sound at boot

[Mark Allums <mark@allums.top>]

I have a decent setup with an ASUS ROG motherboard (overkill for Linux, 
I know).  I was tooling along nicely, when, after an update (back when 
Jessie was Testing), sound quit working at boot.  Of course, the first 
thing I tried was


root@persephone:~# modprobe snd-hda-intel


and that got me sound again.  However, I have to run it manually after 
every boot.  What steps do I need to take to get it to load at boot 
again?  Re-Installing ALSA does nothing, of course, and I guess I have 
no Google skills, because all I can find with Google is advice to 
reinstall ALSA.
