Now, I would like to have it so that when I put, for example, a football stream on the TV, for the sound of the Stream to come through the TV, whilst still being able to play music, games etc on the PC monitor.
The problem I encounter is here

I only have the option to choose a default sound device. I can either choose the PC speakers OR the TV. Does anybody know of anyway to get the sounds to both be useable at once? Am I missing something obvious? I feel like this should definitely be possible since two Speakers and the TV both use different drivers...
Cheers if you can help!
