Holger, I have a question regarding your very good instructions below.
As far as I know Alsa handles all the 1818VSL and other USB interface
connections..
How is that going to influence my abilty to use audio interfaces as now
alsa wont be able to access the usb ports directly when I follow the
link advice you included in your message. If I understand it right
Otherwise
I will write a script with a rollback section so that other people dont
have to battle with jack unnecessarily which is currently the case.
I will try to do something constructive for jack, and hopes it will
solve my problem. If it does I will post the script. There is just about
NotHING available to help new jack users unless they come here.

Good luck.
I am hesitant to use jack as it almost never work
consistently,
pulseaudio at
least works. If I uninstall pulseaudio I will lose all my bluetooth
enabled
ipads and galaxys etc. That works just great. Pulse has other problems
being a
systemd applicat5ion there is a lot of built in garbage I agree, but
wihout it
I dont think anything can take its place currently.
The problem isn't jack but the multitude of audio systems with Linux.
The biggest problem for a jack newbie is to reliably keep Pulsaudio
away
from the audio adapter hardware. It grabs the adapter and then jackd
can't use it.
Solution:
Configure Pulseaudio NOT to use the soundcard but jack-sink and
jack-source, so it outputs to a running jackd.
There are many ways to do it. I use /etd/pulse/default.pa with
load-module module-jack-source
load-module module-jack-sink channels=2
The addition "channels=2" is important when you have an audio interface
with more than 2 channels, e.g. the Focusrite Scarlett 2i4. Without
"channels=2" the SoundCloud player sounds odd because Pulseaudio
fiddles
around with the channels. Maybe there is another solution, too.
