Hi,
I have a DAC+ for few years. I use the steel case (https://www.hifiberry.com/shop/cases/steel-case-for-hifiberry-dac-pi-4-2/), and since few days, DAC+ connection is frequently lost, it now stopped working when I use the steel case (ne sound, green led off).
I tried without the case and then it works fine.
What could it be ? Spacers too short ? Electric current that pass through the case ?
How can I solve this ?
