Toggle keys on but no sound

I noticed that when I hit the cap lock there is no sound. I went to Settings/Ease of Access/Keyboard and the Toggle Keys is on.

I was going to try "troubleshooting" the problem with audio10.diagcab, but I get a pop: An error occurred while troubleshooting. A problem is preventing the troubleshooter from starting. (see screenshot)

I ran the troubleshooter in Windows for audio and at first it told me to open the Audio Enhancements and select, or de-select. I can't remember for sure what it said. Before I could go any further with that another box popped up telling me the troubleshooter made some changes to my system, as shown in the screenshot attached. So I tried the Caps Lock key again and it still won't make any sound.

I've had this problem since fall of 2017 and haven't been able to get any Num Lock and Caps Lock beeps to work. Also, I've noticed that when dialogue box warnings pop up, like when closing a document before saving, those warning sounds don't work.

Have you found a solution to the problem to share?

No I haven't. Someones they work and sometimes not.

I noticed that I had no beep tone with Caps Lock after updating to Win 10 -1809.

I was able to get the beep working again by turning on mono audio. Settings > Ease-of-Access > Audio > Turn on mono audio.

I was able to turn mono audio back off again (and still keep the beep) after turning Toggle Keys on and off and restarting. TBH, I'm not 100% sure of the exact sequence because I was trying a lot of different things. But, the beep definitely started working after turning on mono audio and I was able to turn off mono audio and still have Caps Lock beep.

I too had this problem recently, probably caused by a Realtek driver or Windows update - or both - and the solution offered by KevinN worked but I wanted to know why

The real culprit is the Spacial Sound (Windows Sonic for Headphones) utility, when this is off the toggle keys sound works properly but when it's set to on the toggle key sound is anaemic and barely audible.

So the reason Kevin's solution works is that setting sound to mono disables the spacial sound feature and when mono is then turned off the spacial sound is enabled again but, crucially, it is set to off and the toggle key sound continues to work properly.

I also did hear the Toggle Switch-sound, but indeed it was anaemic and barely audible.
But when the Spacial Sound (Windows Sonic for Headphones) is set to off, now the sound is OK.
Thank you Gorden2 for this tip!

While the above did not work for me ("spacial sounds", whether on or off), I will share that what DID work for me was to use the "additional device properties" (on that same page as "spacial sounds"), which opens a windows called "speakers properties", and from there I chose the "advanced" tab then in the "signal enhancements" section, I unchecked "enable audio enhancements". After clicking the "apply" button, tapping the caps lock did make the toggle keys sound (assuming that feature was enabled). (If it doesn't, you may want to check the setting to enable it, as it may help you for other reasons. Then click apply or close.)

For readers not readily finding the "spacial sounds" page discussed above (you should be able to search that phrase via the Windows search feature), there are various ways. For some, the simplest may be to use control panel>hardware and sound>sound, which will open a screen showing your speakers. Click the one you think should be producing this sound (it may have "default device" and a green check mark indicating it's the one in use for you), then click "properties". That will open the same "speakers properties" I referred to above, and you can follow the steps there.

Hope all that helps someone else. My thanks to those above, whose suggestions got me close enough to keep trying other nearby possibilities.
