No signal from SPDIF/Coaxial out

Hi, All of a sudden I’m not getting the SPDIF out from my HifiRose RS150B. I checked the DAC with other sources and it works fine, so it’s definitely the RS150B. The USB output is working fine. Please help? Thanks

Hello,

Are you saying there is no signal coming to your external DAC?
Or is the input signal detected, but no sound?

Would you try factory reset?
