Ok so here is basically a rundown of this error…
I start my computer and boot up discord. My microphone is working as usual.
I start up FF14, and as soon as I log in and the .exe launches my microphone in discord decreases in quality substantially, my friends tell me I sound like a robot.
After a few seconds or minutes my microphone stops picking up sound at all as if it is not plugged in, and then it also usually starts plugging it in or out, as if my Windows system is rapidly switching between microphones or as if someone is plugging the usb in or out. I can hear the windows sound for removing and putting in a usb device while this is going on.
Usually I just get angry and mute discord and play in silence, but most often after playing for a few minutes I can just hear a static errrrr sound and then all audio on my pc disappears as if the sound drivers just died. No game audio, no system audio, discord audio etc.
At this stage, when I try to open my audio sources in control panel on Windows, nothing happens and the control panel freezes.
When I turn off my computer at this stage it takes up to 5 minutes and 30 seconds for the computer to fully turn off which is very unusual since it normally only takes a couple of seconds.

This all started I'd say 2 weeks ago suddenly. I had played a good 150 hours before any of this started to happen.
