I am unsure whether my device hardware has failed. The log on https://raspiaudio.github.io/ shows nothing, but it connects fine. I am trying to install new firmware. I tried resetting, and pushing the secret button, during boot, long time, short, nothing works. When I power it on with the switch while connected, sometimes the log window shows gibberish, never any real text.
Anything else I can try, or do I need to open a warranty case?
