Wich FW-Verion is it? How to get it?
Firmware 1.0.3 public beta is fixing SPDIF-Out compatibility beside some other issues. Some users are experiencing, that SPDIF-Out is switched off after the upgrade. You can overcome this by Initializing Global Settings (pushing and holding the SYSTEM-button while you switch on). However unfortunately 1.0.3 is introducing a kind of distortion (ring tone) on SPDIF-Out, which we are now working on with high priority.
In the meantime user, who need SPDIF-Out and didn't have compatibility problems before, should go back to 1.0.2 public beta temporarily.
Those, who had compatibility issues before, are invited to open a ticket in our support system and I'll send them an intermediate version, which had solved the issue and delivered clean tone.
This is just a holding pattern until we will release our final fix.
