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.

Hey, Barry,
Thanks for the reply. Frankly I have no idea at all the last kernel
version in which audio from non-DVD sources worked properly. But the
sound for me, where it has worked, has always worked both from the
onboard speakers and from the headphones... and I could easily switch
back and forth, playing from the speakers, then plug in headphones and
play from them... and back again. So your situation and mine are
different... which isn't necessarily to say that a problem can't
manifest itself in slightly different ways. I'm just saying that I'm
not convinced the problem I have is/was caused by a kernel change. In
any event, I wouldn't want to go back to an old kernel version. There
were some major security patches in the more recent kernels and I
wouldn't want to introduce those vulnerabilities back into my system. I
think I'd rather go without the system's sound.
Thanks++,
ken
