Sound/Screen Problems

[XODreams]

Hey so i just downloaded plutonium and when im playing Bo1 i get no sound in full screen while im using an HDMI from my laptop to TV this also happens in bo2 aswell. So i made my screen Windowed and the sound came back on both, now whenever i try to go to zombies mainly on BO1 it just says connecting (im guessing to online) can anyone help me so i can get Sound and be able to play on my TV.
I can provide logs for BO1 if you need them

EDIT: So you know the connection notification stays indefinitely, It never changed in 20 mins of waiting just wanted to point that out.
Also when i played in Fullscreen with no sound the game worked and i was able to hop in to Zombies

I’ve had the same problem and I found the solution to simply put your audio output on your pc to the pc’s native speakers. It makes no sense, but now my TV plays sound (with HDMI connected from my laptop)

Edit: The loading screens will still play on the laptops native speakers, but the actual gameplay audio will play on the TV. Really wierd i know, but hey, it works
