so as an update, now mine works again, im using a tp link hub with and i connect to power of it too, also im using a shorter usb c cable for power, i feel like problem is power related, it shouldn't have this problem and i should have it checked by them but in my case i cant be playing the dhl ping pong with this idiots cuz i live abroad... if you wanna check if you have the same problem with yours, disconnect your dac, bot cables, let it refresh for 5 minutes and reconnect, check with different cables, if it works yoy might have the same problem as me
