Dmr bridge no audio being passed & setup radio to node

OK I knew the old stuff, some of this is the same, however most is too confusing

with the help of Steve I was able to modify files and setup the node
I followed each step, verified it was working
seems the node is reporting to brandmeister and echolink

however I cant figure out how to do a simpleusb-tune-menu to configure the audio levels

I want to add my ars usb fob & a baofeng bf888 to it

Im lost again at this point

any help is greatly appreciated
