[Jack-Devel] Jack Problems

Thanks John.

Yes I have been using command line startup of jack as the preferred way 
for about a year now. It was always the only way that would work.
Before I wiped the AV installation, mixbus did work, but UI had to 
completely remove qjackctl as they did not ant to work together 
properly.As soon as I start qjackctl mixbus wotn work. I let mixbus 
start jack, then the only reson to use qjackctl is just to monitor some 
output. So yur suggestion in my opinion is the correct one.

The problem seems to persist,  using qjackctl with mixbus, so the best 
is to remove it.
Patchage + command line startup of jack seems a better way to create 
connections and jack at least runs and I already did that. The inputs of 
mixbus doesnt seem to get anything from the 1818VSL though and I will 
have to find a way to test them independently from mixbus.

The big problem is to COMPLETELY remove pulseaudio, I dont mean 
uninstall, purge and  make sure there is no panel apps running. I found 
the latter to have created an issue and jack started working after all 
that garbage was removed.

Yes, I worked through the arch document.

Thanks for the input.
It is helpful.
