Question Anything I connect via aux port is not being detected by my PC

[borg.jake.2611]

I just changed my CPU and upon startup, anything when I connected my headphones and speakers to the front panel jack and back panel jack respectively, They were not detected. HDMI audio is working (it is connected through my GPU) but I cannot seem to figure out why the stuff I connect to the front panel and back panel are not being detected. I've tried restarting, troubleshooting and even tested the devices on other computers to make sure they are not damaged. Please help.. Thank you

When you say you changed your CPU, is that exactly what you changed or by CPU do you mean your whole computer?

Does device manager show the sound card installed and working with drivers? Is aux in only thing not working, headphone and mic jacks are OK? What are you connecting to the port?
