I've checked out a dozen or more "solutions" (such as the one here), but my problem seems to go deeper than any of them.

It all started when I built wine. I installed a few dozen dev and other packages. I can reconstruct the list if necessary. I rebooted and came back to the desktop and sound was gone. I clicked the audio control icon and saw only "Dummy output" where previously my actual audio controller had been.

So I tried various suggestions I found online and the upshot was, even the audio icon disappeared. Now my system can't even access my sound card:

$ lspci -v
[excerpt]
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio > Controller
  Subsystem: Lenovo 82801JI (ICH10 Family) HD Audio Controller         
  Flags: bus master, fast devsel, latency 0, IRQ 11
  Memory at f4700000 (64-bit, non-prefetchable) [size=16K]
  Capabilities: <access denied>
  Kernel modules: snd_hda_intel
  sudo modprobe snd_hda_kernel
  modprobe: FATAL: Module snd_hda_kernel not found in directory /lib/modules/4.4.0-24-generic

I've uninstalled and reinstalled pulseaudio and alsa, twice. I even reinstalled the Linux image itself:

sudo apt-get install --reinstall linux-image-$(uname -r)

None of this has made any difference. Is there anything else I should try before reinstalling and forgetting I ever heard of wine?

Two-part solution. The first part I found by trial-and-error:

Removing the oss4 packages:

sudo apt-get remove --purge oss4-base oss4-dev

restored my sound immediately. I didn't even have to log out, much less reboot. However, I still had no sound icon.

A search on that problem led me here, which told me to install package kmix. I tried it.

It didn't restore the sound control panel I had -- it gave me something much superior to what I had! I really like being able to control event sounds independent of the general device volume.

So I am back in business without having to reinstall. What a relief.

I am marking this as the Answer, but if someone comes forward with a more straightforward explanation or troubleshooting advice when the sound card is truly not seen even at the module level, I'll relocate the answer check mark.
