After updating Win 11 to the latest MS update kb5022913 it totally diasabled my Sound Blaster AE-5. I noticed the next time I ran msfs that my speakers weren’t working. My headset which I run through my Thrustmaster Flight yoke was fine. I just use the headset for ATC comms. All other sound goes through my speakers. Testing in control panel failed also for default windows sounds also. After thinking about it the only thing that had changed was the update kb5022913. I uninstalled it, restarted and all audio was back to normal ( windows default and MSFS audio). When I have time another day I’ll reinstall the update and verify that is the issue. I wanted to put my issue out here and what resolved it for me in case any one else runs into the same issue.
