@arox Previously I though the same, so I double checked it. I don't find any problem with DNS, NFS or Wifi. Plus I can connect to the HB without any problem.
@zador.blood.stained I use SPDIF what connects to DAC.
in meantime I tested it with Volumio "distro", there is no delay in this case. Volumio based on Jessie 8.7 also.
