I can't use my headphones. I don't think that the thing is broken. Did Kaspersky blocked the ability to use the thing and if it did, how to solve it

So I can’t use my headphones anymore. I plugged it in and the thing wont work. It happened since I download kraspersky. The application seems very trust-worthy but this problem is weird. Do you have any idea how to resolve the problem? Does it have anything to do with trusted application?

Hello @Bacillus, 

Welcome!

1. Which Kaspersky software name & version is installed → please Read before you create a new topic! for reference? 
2. Which device OS & build? 
3. Check Kaspersky Reports, are there any events related to the headphones or sound?
4. Check Windows Control Panel\All Control Panel Items\Sound?
5. Check Windows → Manage sound devices?
6. Run Windows Audio troubleshooter? 
7. Check Windows Device manager, look for any  alerts marked with⚠? 
8. Do the headphones work if plugged into another device, a mobile phone for example? 
9. Since installing Kaspersky, has the computer been shutdown, using Shutdown, not Restart, then powered on & logged in, make sure Kaspersky software is running, check headphones?  

Please let us know? 

Thank you🙏
