I got two recommendations:
a) Used 'alsamixer' to unmute all channels. The were, as a responder
suggested, muted.
b) Installed kmod-alsa from elrepo. It produced a bunch of warnings
which I ignored.
c) I performed lspci | grep -i audio, and got
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset
High Definition Audio (rev 06)
01:00.1 Audio device: nVidia Corporation High Definition Audio
Controller (rev a1)
got
No sound, and the mute button on the function display does nothing --
it's a constant orange color.
I am not sure where to go from here.
