It was working fine but apparently for some reason it just stopped working. I was trying to configure my Firefox browser to direct its sound on the built-in speaker of the monitor while my game (MH World) is on the external speakers.
Now I'm curious if there is a fix without reinstalling sonic studio and all the realtek drivers.
My motherboard is: ROG Crosshair VII Hero (Non-Wifi).
