I've seemed to had this problem for a little while now (not when I originally got the PC though), but alas I haven't found any resort to it.
My headphone in/AUX input doesn't seem to register new inputs when I plug in cables. However if I restart my PC, it still doesn't register the connection as a NEW input, but it uses it as a default. So I've gotten away with this problem as long as I restart the PC. But it's starting to get a bit tideous- and lately I've had multiple soundsources at once, and the computer seems to be using audio outputs at random then (I use bluetooth headphones too) . I believe it's all rooted in this problem of the PC not properly detecting the jack connection.
Any ways to go about this? PC and audio drivers should be up to date.
Haven't tried factory reset as that is a heavy measure to make since I'm working on some projects right now. But if that possibly could resolve my problems, I would prioritize doing it ASAP before another big work project.
Windows 10 has a reset feature that repairs your computer by reinstalling the operating system. This feature is recommended for recovery because it reinstalls Windows 10 while either preserving your personal data and customizations or removing all your personal data.
You have a choice of two methods to reset your computer.
If Windows 10 loads correctly, see the section titled Perform a Windows 10 system reset in Windows in this document.
If Windows 10 does not start correctly, see the section titled Perform a Windows 10 system reset through Windows Recovery Environment in this document.
