First up – PROBLEM SOLVED, yeah!
In Resolume – Go to ‘Output’ and uncheck – ‘Show Display and Slice Info’.
Again, apologies for being certain this was a ‘Syphon Recording’ error, I had the wrong understanding of how Syphon works.
I am currently on the road without my soundcard so can not emulate exactly. However I’ve updated to ‘Syphon Recording 11’ and only current sound devices are appearing to select from.
I’ll try and emulate with other sound cards and report back if there are issues.
Thanks again for helping fix these issues so quickly, this software is a game changer!
