Recently I have been running into this problem. While on discord, just playing any game, or just being on my Windows 10 PC, the audio would just completely turn off. I tried to troubleshoot it and it said that my headphones were not plugged in, but they were. I tried updating my drivers, updating it to High Def. Audio Device, etc. I have been updating the drivers of my headphones themselves to the High Def. Audio Device which I now realize probably wasn't the best move. Restarting my pc, looking up every video to solve this issue; nothing has worked. I would appreciate any help given, thanks!
