It's weird for me but it happened lately. Whenever I do a first boot in the morning or turn off my psu and unplug my ups through wall socket. But If I restart my pc issues gone.
Seems my audio devices can't detect by Windows. By the way I'm using 2004 version of Windows.
BTW I tried to reinstall my audio driver but it still occur.
It's annoying.
Even my Arctis mic is gone.
