The vvv is important, because it provides more information, including an
output profile over time, a rough vu meter. That is, it will show if
aplay is actually sending output to the device.

hat's itnteresting in that when I feed aplay a tone, only happens in
this computer, the volume begins low and increasesover a second or two,
very noticable but not a problem I was bothered by.

And the output is being processed through the default device, which is
the link between alsa and pulseaudio.
Yes I keep seeing that, looks like the connection between aplay and
Polseaudio is open ...
Can you check in pavucontrol that the default device is actually your
device 0, the analog sound device? Or just do a
cat /etc/alsa/alsactl.conf
°
[bobg@Workstation-1 ~]$ cat /etc/alsa/alsactl.conf
#
# ALSA library configuration file for alsactl tool
# (/usr/share/alsa tree is not necessary for alsactl)
#
ctl.hw {
@args [ CARD ]
@args.CARD {
type string
default "0"
}
type hw
card $CARD
Everything says sound should be playing.
If you do
alsamixer -c0
are Master and Front showing 00? Is the volume in the bar above 80%?
The essential ones are OO and up to the red, "L{NE" was muted I set to
MM and turned the level up, that does not restore the sound though.
