Happened occasionally with atomiswave when I used to stream. My "hotfix" was just switch the input an then go back so it resyncs the signal.
A permanent fix would be much appreciated.
I didn't want to mess with the settings too deep yet, was a bit concered to damage the hardware.
I actually don't have any clue.
Any other board I tested was fine.
But Atomiswave already gave an unclean image on ossc with the axun board.
I happen to have also a Hydra scart switch and this device, cleans up the signal. But I think that there has to be a solution to it, without chaining any...
