[SOLVED] jack server no start: "hw:II" (No such dev)

I can't tell if this is a hardware recon issue or what.
This is on an asus g73 ROG laptop, haven''t tried
it on my desktop yet.

The complete error message when attempting to
start qjackctl is:

What is the output from the following commands?

cat /proc/asound/cards
aplay -l
aplay -L

I put it up here (1 week) where it doesn't get scrambled (didn't try here):

https://paste.opensuse.org/2213c656

the top half is Devuan, the bottom half Suse Leap-15.3

Not likely to be a factor but under Leap I have qjackCtl set
up to run  *pajackconnect.bsh* at start and stop.

You only have two audio interfaces, so I would expect them to be labeled hw:0 and hw:1
Do you want to use the on-board audio or the nvidia?

I think one of them is HDMI, beyond that it's chinese 2 me

I went to the Leap install and took pictures of the setup pages,
comparing them I saw that on the Devuan install it showed

Output Device: hw:II,0
Imput Device: hw:II

Changing both to (default) fixed the prob.

I haven't done the Leap setup for ages (probably
just copied the home folder with each upgrade) so
I don't know where those '(default)' settings came from.

Thanks for giving me a hunch...
