So I always switch between my headset and my speakers for sound feedback on my computer, so what I do is I right click on the sound symbol at the bottom right and click on "playback devices" now this should normally have a window that pops up with my audio devices that I can switch in between and set which one is my default sound device. Now what is happening is nothing at all.. for a split second it shows a loading mouse cursor as if it should actually be doing a process of opening up my audio devices, but nothing appears. Now I tried searching my computer via the windows 8 option and clicking on "manage audio devices" but when I click on it, once again nothing appears. This issue is quite aggravating as I have no idea what is going on and when I check my task manager I don't see any window that is currently running.
