Comment 33 for bug 363892

Ok. Here's a big hint. All I have to do is edit and save /etc/modprobe.d/lanai-sound. To start, I had

options snd-hda-intel model=dell-3stack

When I commented this line out and restarted, I had sound. To check, I tried restarting a second time. No sound. I then went back and added and deleted a whitespace to the lanai-sound file and saved it. Note that all the lanai-sound file now has in it is the options line above commented (#) out. Restarted the inspiron and sound came back.

So it's not the content of lanai-sound that matters. It's whether it's new or not. What is that about?
