AOC G2460PF built-in speakers problem

[Lizardspit1]

I recently got this monitor and for the first week it was working fine, but now there's a big problem which is making me consider returning it. Whenever I want to use my mic on my headset the sound stops coming through my headset and starts playing through the monitor speakers. Note: the mic works just fine because I can hear it play back through my headset and I've tried it on two different headsets and still have the same problem; it only starts having this problem whenever I try to talk in a Discord call, Skype call, CS:GO voice channel, Teamspeak, etc. I've tried reinstalling drivers on both my headsets and on the monitor manually, but that doesn't work, and I've tried to look for similar cases on the Internet but it seems like I'm the only one that has this problem. Anyone have an idea?

try another hdmi cable even for testing purposes.
