Tom, I completely agree with you.
I don’t want to offend any Hifi Rose user either, but many guys just want to listen to music and everything should work perfectly for guys like that. But that’s not the case and you should spend a little time dealing with technical details like that.
Yes, when you restart (of course I know the function) on the device or in the app remote control, the device is briefly disconnected from the power supply. But there are also capacitors built into the device that still give off residual voltage for a certain amount of time, so that the RAM is still supplied with power. I’m not an electronics engineer and as I said, @Edwardmos could try it. Otherwise, it might have to come from the software side.
But these are just my guesses.
Have a nice weekend, my big boy
