Did a clean install on a reformatted the SD card with a downloaded 2.834. Seems to be working so far.
I can control volume, see and play tracks on the NAS and credits are available.
Not sure what happened with loopback. At one point among these resets loopback appeared then on the next reset it was gone.
I’m suspect that all features are functioning normally, but for now the critical thing is I can listen.
Will add the parametric EQ next and hope for the best.
I appreciate the attention to my original post.
Given the time difference I don’t expect real time support, but something more helpful than “reset and let us know” would have been nice.
Maybe its my WIFI, but I’ve concluded that over the air updates and factory resets introduce more problems than they solve. In future I’ll just do it the old fashioned way.
