Ineithercase,theserverwillindicatethatyouneedtostartaclienttoconfigureyourspeakers.

Similarly,whenyoustartupaclient,youwillbetoldthatthereisnospeakerconfigurationfile,andaskedtocontinuewiththeconfigurationprocess.Oncontinuingwiththeconfigurationprocess,youwillbepresentedwitharepresentationofaroom,andaseriesofconfigurationcontrolbuttons,asshownbelow.
