Parcel next to mine can hear my youtube. I have checked the box on my parcel.

I have checked the sound box on my parcel so that my radio does not leak over my property lines.

But the next parcel can hear it.  The cannot hear my radio. Only the YouTube coming from my TV. Help!  The landlord could not help. they are the ones that live on the next parcel. :)

In the Sound tab in World >>> About Land, the option to Restrict gesture and object sounds to this parcel will keep streaming audio that you have identified by putting a URL in the box on that page. It will not restrict sound associated with a media stream that you identify in the Media tab.  You do, however, have another option.  You can use shared media (also known as Media On A Prim ) to play your YouTube video on the face of a prim.  Read https://community.secondlife.com/t5/English-Knowledge-Base/Shared-Media/ta-p/700145 . When you use MOAP, you are displaying the video in your own viewer, so other people around you do not hear or see it.
