Dear Muhammad,
Unfortunately, we can’t provide feedback without seeing the whole project and view how you created and added the audio and video signals. You may email me your project as zip file to ahmad.atieh@optiwave.com and I’ll check it and provide feedback.
I need to know the version of OptiSystem that you are using and your institution. Also, I need to know if you have valid maintenance and support license.
Regards,
Ahmad
