Roon maps 7.1 to 2 ch with hapi dac

I used acourate to create 8ch convolution for roon to run the hapi dac but it only plays on 2ch ( map shows 7.1 to 2 ch )

Jriver works fine but the device setup in roon does not show a 7.1 option under advanced ( it does not show anything)

All settings in hapi and roon seem to be correct.

Anyone else solved this.

Thanks

Phil
