Hello J.udooon, welcome to the Microsoft community, I'll be happy to help you today;
I understand that you are having problems with the audio in Windows 10;
What exactly is your PC model and manufacturer?
If it's a desktop, what exactly is the model and manufacturer of the motherboard?
Before answering this question I suggest you run the Windows 10 troubleshooter;
Press Windows key + i and go to Update and Security;
Click Troubleshooting and then Additional Troubleshooting;
Select Playing Audio and click Run the troubleshooter;
Check if the problem has been fixed;
Check that the output device is correct;
Right-click the sound icon on the taskbar and go to Open sound settings;
Under Choose Output Device, click the drop-down menu and set the correct speaker;
Check if the sound works normally again;
Hope this helps, see you soon!
