Firewall access ruining sound?

[Riift]

So for the past year or so i have had a problem with sound in a game (Rainbow Six Siege). I assumed it was just due to the game and not my pc so i just left it. Recently something changed which fixed it and im not sure what. I was playing Rainbow Six again today and decided to leave it and update/delete some things. I ended up updating Fortnite and then opening it. Upon opening it, the game asked for access to the firewall (i think this may be the problem). I clicked ok and the game loaded ok but eventually the sound just stopped working and my pc started blasting beeping noises through my headphones. Now my sound still works but just sounds a lot different to when the problem was non-existent (certain sound features in-game do not work though). Has anyone else had a similar problem or may know how to solve this?

the windows firewall pop up really only changes access to your network, not so much aspects to an application, and highly unlikely your sound

 

how are you getting sound through your system? is your system sending sound through display connector? what does your device say for your sound devices, have you tried a usb soundcard / updating drivers?

I have built in sound in my motherboard im pretty sure. I am using heaphones so it is directly through the aux cord. I havent tried much as the problem only came back today, after loading fortnite. Would it possibly be to do with Windows Sound Enhancements as after exiting fortnite a pop-up appears saying that the enhancements may be causing an issue with my headphones
