PC not detecting any new output device

My pc doesn't detect any new output device outside my monitor's audio. I constantly have in the device manager two high definition audio controllers, one is working fine, the other one can't start(i don't know if that's the issue). The headphones for sure aren't the issue since they're working everywhere else. I tried to fix by manually downloading realtek audio drivers of my mobo from the manufacturer and format the pc completely with a fresh windows install but nothing fixed. I didn't do any updates and I don't have any new update to do, so I really don't know what the issue could be.
