Thanks for replying!

They may have changed it to 'alsactl store' else just typed the wrong
word -- save, store, whatever to us humans! <g> This newbie did a
Google search and found the storage goes to /etc/asound.conf -- which I
don't have at all (!). Significant?? Or just empty because I haven't
stored anything first?
And as I reminded Nick, in System Settings I don't have a 'Sound' icon.
LIS originally , not sure if that's significant.

I wonder if that's what happened on my old Mythbuntu system (RIP -- late
last week I think the storage drive died) Rarely had to reboot one of
the Frontends to get sound. (That's the reason I'm using the old HDMI
cards - trying to get them to connect to the new Backend.)

Like this newbie knows much of anything ... ah heck: thought I
remembered I had something in my notes but was "if HDMI audio pass
through does not work".

Right. I've found a lot of stuff when Googling trying to figure this
last portion out and 'sudo' isn't written. I usually figure if it
doesn't work as user 'barry' I just have to tell the computer who's boss
with the 'sudo' nametag! <g>
Anyway, thanks for the help! We'll get this critter working yet!
