|Thanks for the reply, Zicrest.|
I have done as you asked, and also changed my automatic updates to only let me manually install but notify me. Is there a way to find out about previous automatic updates when I undo the restore? (To when the sound is not working)
There is currently nothing under Multimedia devices when the sound is working, I am about to undo the System restore point and will post if there is anything there when sound is not working.
After restoring to the point where the sound does not work, there is nothing under the Multimedia tab. It is also worth mentioning something else, when the sound doesn't work, it weirdly enough works when I click the sound test in Realtek HD Audio manager, under the 3D Audio Demo section. It works nowhere else as far as I have seen.
