Windows 10: My computer won't pick up my voice without headphones

My model is: G512LIMy computer can pick up sound fine through my headphones, but it won't pick up my voice without headphones just through the computer and it used to. I am not sure why it does not anymore. I have tried troubleshooting, updating drivers, and it says there are no problems. But there clearly is. Discord, Microsoft teams, etc. won't pick up my voice on the microphone. I have tried googling it but I am confused exactly what to do as a lot of microphone issues are assumed to be related to headphones. This computer is not even two years old, so I know that is not an issue. Please ca

Microphone only picks up audio from headphones?

I currently have a pair of razer kraken pro v2's which are plugged into my computer via a headphone splitter. My computer detects my headphones just fine (audio working and all), but when it comes to using the microphone it doesn't seem to pick up my voice at all and only picks up audio coming out through the headphones.

(EDIT): My microphone can now pick up my voice, but it still picks up sounds from my computer. Any way to fix this this?

 

Bluetooth Headphones only connect to voice and music

Today my headphones started to only use voice and music, when yesterday [the day i got them] they did all noise. I have re paired the headphones to the computer, remove and re add them to the computer list, and remove the computer from the headphones bluetooth
list. Everytime I reconnect them they just say connected to voice and music.
