HOW TO FIX THIS?
this always appears, why?
and i can't open to change properties
i use U-PHORIA BEHRINGER UMC 404HD
I've never seen this before, but you can check in device manager for your 404HD. It should be listed there and it might tell you there's a problem by displaying a yellow exclamation mark. Whatever it shows, you can try reinstalling the drivers. You can find them here: https://www.behringer.com//Categories/Behringer/Computer-Audio/Interfaces/UMC404HD/p/P0BK1/Downloads...
For Windows 7-10 try the latest version 4.59. If that doesn't work or you have an earlier version of Windows, try v4.38. Other than that, you could do a web search for that particular error code to look for more insight into the problem.
