Prior to the below the sound/audio on my system worked just fine.
Then a yum of install of audacity with dependencies:
...
Downloading packages:
(1/6): vamp-plugin-sdk-2.5-4.el7.x86_64.rpm | 172 kB 00:03
(2/6): wxGTK-2.8.12-20.el7.x86_64.rpm | 2.9 MB 00:00
(3/6): audacity-2.1.1-1.el7.x86_64.rpm | 4.3 MB 00:08

(6/6): wxBase-2.8.12-20.el7.x86_64.rpm | 588 kB 00:10
...
Now nothing which is supposed to output is working; e.g., something as
simple as "play file.wav" hangs at the start and outputs no sound at
all. Two minutes prior to the install the exact same command worked.
Same story with other apps using sound.
I "erased" (rpm -e ...) all of the installed packages listed above. That
didn''t fix the problem.
My guess is that the install loaded one or more bogus kernel modules, it
would be nice if lsmod showed WHEN the modules were loaded, but it
doesn't. Is there some way to find this out?

snd_hda_intel probably isn't the offending module anyway.
I recall having this same problem five or ten years ago with an audacity
install, but don't recall what I did to fix it. Anyone here closer to
this issue?
Thanks much.
