Along with the LED lights not working currently, I believe an update to either Discord or Windows 11 has broken the EVGA Nu Audio Pro with Discord.
For the past two weeks I have had an issue where Discord will randomly mute all voice communication. Almost like it is switching audio devices. I can talk and be heard, but I cannot hear anyone else. The names light up and indicate they are transmitting.
If I switch my audio device to my speakers (Razer Nommo Pro) and then back to my headphones, it works again momentarily before randomly muting itself again. Doesn't matter if I restart my PC, reinstall the drivers, reinstall Discord, the issue persists.
I have since installed my Soundblaster AE-5 and in the past few hours since, not a single issue as I was having before.
Just some food for thought. I did open a ticket with Discord and can do some additional testing.
