Unable to hear first officer checklist

[Bighoss123]

Hello I am going through the checklist however I cannot hear the first officer. All volumes are up in xplane and everything is checked off in the Cl650 menu.

Can you please check this topic and make sure you are using the correct checklist bindings? The checklist commands are also accessible Challenger 650 \ Checklists menu. Please note the FO will not speak the checklists if you advance the checklist using the DCP controls - you must use the specific checklist commands.
