So, recently I have bought a pair of logitech G733 headphones and when I play games like Cs:go or Valorant my mic stops working (sometimes it turns off, not always), and I can't talk on the game or on discord. I fix this problem via re-connecting the usb to my computer, but it comes back after some time. (this happened with my old headphones as well), I can hear audio, it's just my mic.
Make and model of your older headphones? If the other pair was an USB driven headphone as well, might be an issue with your USB ports. I'm assuming you've got Logitech's G Hub app installed? If so, what version are you on?
Please share the specs to your build like so:
Please check to see what your BIOS version is as well. If you're working with Windows 10, please mention the version(not edition) of the OS.
