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
