Running Intel Nuc with Windows 7 64 bit.

Earlier version, 23 the wdm driver worked well.
When upgrading to 24 I noticed that I could not use my MCE remote to mute or change volume.
No big deal but since 24.0.30(maybe earlier because I missed one or two versions) it doesnt work at all, no sound at all.
Had to remove wdm driver and reinstall my XMOS driver(using Singxer F1 usb to coax converter)

Tried to actívate wdm driver a couple of times more but it kills all sound.
Removing wdm driver doesnt help, have to reinstall XMOS driver also to get sound back.

That's a problem caused by Windows security changes.  There's a thread on it somewhere on the MC24 board.

But it worked with MC 23?
Tried to search the forum about it but didnt find.

Here is one of the threads on wdm and Windows 10.

Basically, wdm does not meet the current signing requirements for a Windows 10 driver, so you need to disable a security feature (secure boot) in order for wdm to work on Windows 10.

The OP is running Windows 7 on an Intel NUC, which lacks the secure boot support Windows 8 introduced and lacks the driver signing requirements Windows 10 has enforced.

The WDM driver *should* work on Windows 7. Do you still have MC23 installed there alongside MC24? If so, you might wanna uninstall MC23 (as a test at least). You might have to run MC24 as an administrator, and then in MC's Options > General > Features uncheck the WDM driver then finally exit MC24. Reopen MC24 (again as an administrator) and go back to MC's Options > General > Features section and check the WDM driver and then close MC24. You might wanna reboot your NUC after doing this, then start MC24 normally (meaning not as an administrator) and see if the WDM driver works.

It might require (extensive?) code changes to the driver itself in order to get it working. Who knows, it might require a partial rewrite of the WDM driver itself.
