The question would be, does the file gm.dls exist in your Win10 Windows folder anywhere?

Searching for a file in Windows folder can be tricky, as it seems that Windows Search doesn't work in certain folders, I'm not sure why.

So you should manually look for gm.dls in these locations, or similar names if they have renamed them for Windows 10
These are the locations that the file is found on Windows 7


C:\Windows\System32\drivers
C:\Windows\SysWOW64\drivers

C:\Windows\winsxs\x86_microsoft-windows-audio-mmecore-other_31bf3856ad364e35_6.1.7600.16385_none_8cd41e2771e37717
( sometimes inside another folder like amd64 in C:\Windows\winsxs\ )

If you do find that gm.dls file, move it to the folders like C:\Windows\SysWOW64\drivers or C:\Windows\System32\drivers and see if things improve.




Have Fun!
