At this point, I'm about at the point where I just may go and drop another decent amount of money on a different headset, which I really don't want to do.

I play FiveM (A modification of GTAV on a different client, A simple search of "FiveM" on youtube will bring back a ton of videos), and whenever I play it and I use voice chat, People can hear themselves thru my mic and they can hear my friends talking to me if I'm in a discord call with them. I use the provided razer splitter to plug into my PC. I have tried literally everything that I have found to supposedly fix the issue, Making sure to Push the combined jack into the splitter and it always has been, Try a different port on the back of the PC which didn't work, I tried to use a USB splitter for the Mic and Audio (Tried on the front ports of the PC and Back ports) and neither worked.

I am honestly stumped at this point. If anyone could provide any help at all, It would be extremely appreciated.
