Yes, I suspect that Qjackctl saved one of the many iterations I attempted

As I said, I checked it, nothing is muted and all are at

What am I missing...
Ok, simple things first. have you verified with meterbridge or
something similar, that there is audio (needle movement) going to
the
system output ports? Have you tried connecting your audio source to
all audio outputs?
Yes, used meter bridge, yes there was movement.
Cool, that narrows things down anyway. So there is sound in Jackdbus, but
the output is not getting to the hardware.
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.

It looks to me that whatever jackd has saved needs to be cleared out.

See if that works. The first line is the important one. So long as capture
and playback are set separately, device doesn't seem to take effect (for me
anyway). In any case you have three different devices in there and one
would probably work better.
You may have to replace the hw:0 with something better (hw:0 is probably
hw:PCH). I don't know what HD2 is, but if you have all external audio
unplugged I don't think it should be there.
Well that did indeed work.
I didn't change the hw:0.
The output of aplay is:
aplay --list-devices

I'm assuming hw:0 somehow used PCH, it being card 0.
How did you arrive at these values: dps period 128 dps nperiods 2
