I cannot get VDL sounds to play. I don't know if it's a problem in Sibelius, Contact, or other. It's possible that the problem is simple, but I don't know where to begin troubleshooting. I was using the software recently with no problem. Now I don't know what's wrong. Please help.
Welcome to the forum!
Please attach a screenshot of your Playback Configuration, and perhaps one of your fully expanded Mixer.
Do you get proper playback from VDL when in stand alone mode?
