HiFiBerry Dac + Pro XLR and Raspberry Pi 4b with Volumio

It works, but after shutdown I cannot get it to restart? Cannot find it on network. Once had it show up as Volumio internal hotspot but then could not find usb SSD to play from.

I have no idea what is going wrong. But I have had to reformat, use different sdcards to hold volumio and start over with standard settings again and again.

Works great when it works! But almost NEVER can be found after a proper shut down and then power up.

Is there a STEP BY STEP FAQ for my component setup?
Or are there internal config lines I need to edit to make things more dependable?
