Description Of Issue

Hi there Roonies,

Ever since updating to 1.8, when I power off my DAC, the next time I try to use Roon, I need to reboot my core before the DAC is detected as an available audio zone. I also have the core connected via HDMI to the same device (Oppo UDP-205) and that IS detected and available without rebooting the core. This is reproducible every time I power off the Oppo.

Please let me know if I can provide any additional details that might be helpful.

Thanks in advance,



@support looks the same as my issue!
