Yes, used meter bridge, yes there was movement.

That said, since my last post I booted to the original os on this laptop
(it is a system76, so it came with vanilla Ubuntu) the speakers worked.
(Since it was vanilla, I had no jack, etc. to play with...and has been so
long I had to log in as guest, so didn't attempt to install anything.)

So, I rebooted to UbStudio. Now I can start jack and get sound from the
speakers, but it's distorted.

Following is the output of jack_control dp:
