[bobg at box9 ~]$ aplay -lv
aplay: device_list:240: no soundcards found...
I usually test sound with:
[bobg at box9 ~]$ aplay /usr/share/sounds/purple/login.wav
Playing WAVE '/usr/share/sounds/purple/login.wav' : Signed 16
bit Little Endian, Rate 22050 Hz, Stereo
However in this case no audible sound is produced.
Also as was suggested in the past I can run "pacmd info" and see the following:

I'm not sure how to interpret this but there's that "Dummy Output"
again!

"alsa-plugins-pulseaudio" removed and reinstalled using Yumex as a
matter of convenience.

Perhaps re-installing PA will help, but I'll wait 'til later to try
that, it was three in the morning here and I just got up wanting a
cup of coffee. I think I'll see if there is any response to this
data first.

I thank you for your help.
