Oh dear goodness! Now another problem!
After a few minutes, the sound became intermittent; then stopped altogether. When I opened the volume control [Using Crunchbang as my OS now- it opens pavucontrol when you click on the volume icon ] the sound played normally. When I'd close-out the pavucontrol, the sound would stop again after a few seconds. Open pavucontrol...it worked again...and so forth.
Also, the volume icon is not showing the muted symbol...even though it isn't muted.
This is getting ridiculous! (But at least I know that this sound card is good....)
