The www has failed me with this, so I'm trying you guys. Sound worked
great out of the box when I installed 7.2... Yay! I could watch all
kinds of videos, like on facebook and youtube. And I could listen to
most podcasts too. But then something happened. It was either a kernel
upgrade or that I installed vlc (for watching videos on DVD) and the
whole stack of codecs for it... I don't know exactly when, but at some
point I no longer had sound with youtube and other web videos. The
videos played fine, just no sound. Note that using vlc, both video and
the audio with it play just fine. I need to select the audio driver
(from a list in a vlc menu), however, else the sound won't work in vlc
either.
If I go into the Applications menu, then System Tools -> Settings ->
Sound, under "Choose a device for sound output:" there are no devices
listed. There used to be.
If I run "aplayer file.wav", nothing plays (no sound at all) and I get
the error "main:786: audio open error: No such file or directory". If,
on the other hand, I run "aplay file.wav -D plughw:0" (i.e., specify
the/a device), I do get sound, the file does play.
I ran alsa-info.sh and it posted tons of info from it on my setup at
http://www.alsa-project.org/db/?f=1dba91886be054df4816000768a0f5b109947a48.
Yet it still doesn't tell me what's missing.
Anyone here have an idea...? or thoughts about where to look next?

I have similar issue with USB headphones. Worked fine in 7.2 but in 7.3 I
frequently have to unplug and plug them back in before it finally is able to
be selected from the menus as my output.
I notice that you have an HDA-Intel. I do as well. By any chance is the
last kernel that worked reliably with sound is
kernel-3.10.0-229.20.1.el7.x86_64. I find that with kernels newer than
kernel-3.10.0-229.20.1.el7.x86_64 the sound card works, but
the internal speaker is disabled, but I can plug in headphones and get
sound that way. If I boot into kernel-3.10.0-229.20.1.el7.x86_64 with no
other modifications to my system, my sound works fine.
