N10 clipping RME sound card... (solved)

Same project played back in Nuendo 8 and Nuendo 10… RME MADI card in a MacPro, “set device attenuation” is switch off on both platforms.

In Nuendo 8 the project plays back nicely, hits -0.1 and reports the same in RME TotalMix.

Playing back in Nuendo 10, it clips TotalMix so I get lots of lovely crunchy crackly noises, and by lovely I mean horrible.


Following this post.

Check control room configuration. You probably have duplicate outputs.

…Is the correct answer. Blast, why didn’t I think to check that? Control room outs doubled with 2Mix outs. Thank you so much!
