Windows 10: Certain programs aren't being detected by Windows for audio?

I've reached out for help on r/Steam earlier to be told that Steam doesn't control audio, which I expected but tried anyway. Some of the games I have installed on my PC are no longer outputting audio and in the volume mixer sometimes they don't even come up when the game is running and when it does it doesn't show any audio being detected. I've tried everything under the sun that I could think of and find on forums, websites, etc, and nothing has fixed it so far. Any help would be very greatly appreciated. I may be a tad slow to respond as school has started back up for me.

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Icons from apps aren´t displayed correctly






The native apps from the system are all showing this strange square instead of the normal icons. Please help resolve this problem. Thanks

 

programs not detected by "3d Detection"

I cant seem to get some of my 3d programs to be properly detected by 3d Detection.
a couple oldies but goodies, and yes, I do still play them.

UnrealTournament engine games
Halflife engine games

I suppose when I dust them off I could just manually load a profile, but it is much easier to just have proper 3d detection. I noticed an exception list, is there any way to create a list of applications that if detected running, atitool switches to your 3d profile?

I've tried 0.23 and 0.24b1 no success.
Using 5.2 Catalyst drivers.
3d detection verified operational by doom3, HL2, 3dmark2001,2003, aquamark and a few more.
