I have the update KB5077181 but it has been installed the 11th of february and it has stopped to work with the Fireface UC 2 days ago. It works with DAW or other softwares.
In order to make it works, I have to start my computer, turn on Fireface and Faderport8, and reboot... not really convenient.
I uninstalled drivers and reinstalled them but the problem is still there. I have 2 entries I can't remove in Installed Applications (see screenshot).There is an error when I want to uninstall them (2nd screenshot). Is there a way to do a clean uninstallation ?


To be clear, it has stopped to work with no reason (no Windows update or drivers). I did the update to drivers 1.276 and a Windows update (KB5077241) after it has stopped to work thinking it could solve the problem.
I did another test. If I turn on Fireface and Faderport8 before starting the computer, it works. Otherwise, I have to reboot it.
Other thing, if I exit TotalMix and I launch it again by clicking on TotalMixFX_x64.exe in Programs/RME/Fireface, it works. At least more convenient than a reboot but it will be better if it could work as before.
