HMDI sound wont work automatically from system to TV

[tumba_lone991]

Before i used to drag the video from PC screen to the TV screen and the sound would change automatically from PC speakers to TV speakers and now it doesn't and i have to do it manually by adjusting some control panel - sound options.

Does anyone know how i can make this happen automatically again?

Sounds like you have some vendor specific audio control panel in which case we cant begin to help you without knowing what that software is.
