How can I disable the unsafe volume warning?

Some info about my system:

Samsung Series 7, Win10, Realtek Audio Drivers

Anytime adjusting my headset volume past 40 I'd get a "this is dangerous" popup, real annoying when playing fullscreen games.

I solved this issue by going to All settings -> System -> Notifications & Actions -> Realtek HD Audio Manager

and turned display notifications from this app to OFF.

Another way you might do this is by going to Sound -> Playback Options, and selecting a different default playback device if you have another driver installed.

Hope that helps.

I seem to have this issue on my linx 1010B windows 10 tablet. The flippin' prompt does get very annoying when I need to use my device as an source device. As like you, I am also a sound engineer, perhaps the way around this is to use an external usb soundcard, however, this proves very annoying as the device should 

be able to output a modest signal independently. I have not had this problem on either my lenovo laptop, or 2 of my main rendering pc's.

Any luck?

Not personally replying to you but to the thread in general... Why don't they have a "reply to thread" button is beyond me.

In any case, just sharing my experience as it may help someone.  I tried to use the non-Realtek drivers from windows but it isn't fully compatible as my headphone jack doesn't work any more.  I have a Samsung NP700Z7C btw.  So I had to go back to the Realtek drivers.  However, when I went to Update the Realtek drivers, I noticed that my old Win 7 drivers were still there (I did an upgrade to Win 10) because I see the date is 2012.  So I selected that, and bam, no more nag pop up, and everything, including the headphone jacks, work!

Procedures:

Open Device Manager, open Sound, video and game controllers, right click on Realtek High Definition Audio and select Update Driver Software. Then "Browse my computer for driver software", then "Let me pick form a list of device drivers on my computer."

Then I selected the driver with date 2012.  However, if you upgraded from windows 8, and you had the nag there, then I don't know if it will work.  I then Deny System access to the Realtek folder in Program Files so windows/SWupdate can't update it.

The Realtek driver version is: 6.0.1.6716 [8/28/2012]

Hope this helps someone!

This didn't work for me on a Samsung Notebook 9 -- after Step 5, there's no sound device installed at all, so could not find and update any driver. Was able to revert just by changing the Properties so that System can make changes.

I had this same problem. Found out it is a Realtek driver issue, not Microsoft. So if you have Realtek loaded anywhere on your computer--i.e. systems folder, that is your bad boy.

Turns out it has to do with some EU regulation standards and it really sucks! I found the fix and solution on this page: http://www.noach.one/technotip/idiotic-realtek-audio-drivers/

That should do it, it worked for me.
