Max volume on start of playback via Airplay - Naim Mu-so & Mu-so Qb [Solved]

Hi, Sorry But I’m having an issue in the this realm as well… Have read through above but got a little lost as new to roon and the general topic. Excuse my laymans understanding.
On a few occasions now my muso and muso qb are starting at max volume, (which is very worrying as I’ve already had repairs to blown drivers. )
Ive set both the max volume and comfortable volume limits to 55 but it still starts at the muso’s max.
After reading this I Fixed volume and saved, reopened setting but still no option to set max volume (or disable).
Im using a MacBook…
The only option under advanced settings is Multichannel mixing and volume levelling is not enabled…

Im waiting on my new Uniti atom/Totem system … will that system be any different to muso in regard to ‘roon ready’ and ‘Airplay’?

Please help
