I have a Raspberry Pi with the DAC+ADC. The output goes into the line level input of my NAD C326BEE amplifier. I was playing the music for about 5 hours at 20% volume and the amp was continually overheating and shutting off momentarily. It would come back on and play music again after a few minutes.
This does not happen with any other inputs including a turntable or an echo dot running for hours.
Is there some kind of software tweak I can do here? Or is the hardware possibly sending too much voltage(?). Not sure of the right terminology.
