Have you tried to use another headphones?
You need to install the drivers for it. Find the model that matched on your computer.
It can be the other way,
Go to Control Panel - Sounds and Audio Device - Advanced Tab
then check if it is not on mute. Make this thing sure and okay.
Hope this will help you.
Hello, I recently built PC and I plugged my steel series 5H V3 headphones into the front ports (my motherboard had on board audio) but when opening the sound panel it says my headphones are not plugged in.(I'm using the windows sound manager) anyone know a fix? Thanks!
