Ok I will add to the tons of threads regarding Soundblaster card issues since windows updates... So I recently changed motherboard, and updated windows from 17xx to 18xx. Since I did both at once I'm not certain the culprit. As it stands on windows bootup after a period of time being switched off my sound wont work. My sound card will show as SB Recon3d instead of Soundblaster Z, and the control panel for it wont work. Solution: I repair the drivers, or uninstall and reinstall, then restart twice and it all works fine. Problem: I go back to the computer the next day and have the same problem. Its happened a good 6 or 7 times now. And I cant find anyone with the exact same issue or anyone who updating drivers didnt help (I am on the latest drivers).
