audio problem TV 15 Mac Big Sur

frasg

Good evening, I have a problem with the above version, when I go to remote control of the mac from another pc or device I do not hear the audio of the mac ... what should I do? I have enabled the various options and given the permissions but nothing, plus if during the remote connection I touch some audio settings the volume of the mac I access is lowered to almost 0 until I disconnect.
Thanks
