I guess mine is headless too then, it only has power, ethernet and audio cables plugged in. And the HiFiBerry ADC/DAC Pro HAT of course.
I see what you mean now, it saves you having to plug the keyboard/mouse in like I did for setting up purposes.
I did buy a heatsink from HifiBerry but I didn't use it. The steel case they provided seems to give cool air circulation and it doesn't seem to get too hot at all. If high temperatures do cause throttling, I will have to take it apart and fit the heat sink in and see if that helps.
I'll have a look at the Intel NUCs - if the power consumption is low enough for 24/7 operation I may upgrade to that. Trying to keep it down to internet router levels of power consumption or lower if I can
Also, I tried to run jackd1 and this is what happened. Did I enter the command incorrectly?
