What do you mean now, playback or monitoring the tracks ?
The tracks in the jpg are record enabled, and if you have Cubase preferences/VST/ Auto Monitoring set to “While record enabled” the tracks would not playback.
You should not have to activate the tracks to hear playback.
Peakae was asking how you had the Preference/VST/Auto monitoring set as that could have caused your problem. Since you say this is set to “Manual” this is not the problem.
How are your tracks routed, I notice you have a Mute on something somewhere?
