one thing that really annoys me for months is the “disapperance” of my raspberrys in case of a hard reset aka pulling the powerplug.
My last “experience”: the setup gui didn’t appear on one of my RPi 3B+ with Hifiberry Amp2. So, I pulled the power plug, waited 5 seconds and replug it. The result: nothing No sound, no connectivity via app, not visible on the wifi monitor of my fritzbox. Software is about 3 months old (around 2.57+).
This was the fourth time within the last couple of months! Not only with AMP2 (with its separate power supply of 19V), but also on normal ones with piggyback hifiberry DAC.
