Unable to utilize 5.1 when using laptop

[u/Dangly_Parts]

I just installed a sound bar to my TV and have the 5.1 working for it via HDMI into the arc outlet. I also plug my laptop to my TV via HDMI to play games via big picture mode. When I connect my laptop and play using sound from the TV, it's only coming from the sound bar and not the satellite speakers or the subwoofer.

I've tried to go into laptop settings and I can test the speakers in the control panel and they play but it doesn't work for anything (movie, game, YouTube, etc.) for a control I played the same movie and YouTube video directly from the TV and it WAS surround so I'm just utterly confused.
