Audirvana Plus issues with Cambridge CXN

[Simi1947]

Just trialling Audirvana but aware of the audible improvements via my Naim Mu-so Qb so very frustrating when initially it worked from iMac to CXN via Ethernet, but on fiddling with preferences whilst following Audirvana’s guide, the CXN now has “II” paused. The screen fleetingly shows the album cover before pausing. Similarly, changing tracks, via iMac or A+ remote on iPad, causes a flash of recognition on the CXN before pause. I have installed “Early Updates” on CXN via Cambridge Audio website which they helpfully suggested had resolved the issue, but no joy. I have emailed both parties to seek a solution. Would be a pity for their great software and hardware to remain incompatible. Has anybody successfully connected the two, and if so, could you please screen-grab and post your preferences? Thanks
