Well if that wasn't easy to fix.
/Applications
/Sound & Video
/Volume Control
PC speaker was muted...
Then it happened again.
I used the 'Master' volume control on the top panel...
Back to
/Applications
/Sound & Video
/Volume Control
and this time the 'Master' was muted.
So you gotta set preferences in there.
Alrighty then..
I feel like such a newb
What preferences do I want???
I'll just lean over and use the amplifier for volume control
