Everything was working fine until I decided I'd unplug my rig and clean it out as dust had began to accumulate inside it. I have the Coolermaster HAFX case which comes with an audio jack and mic input on the front - something I used very often whilst gaming / when people around the household wanted quite from my speakers!
My front panel audio jack (that I use for my headphones) will only work if my rear audio jack (used for my speakers) is plugged in. The problem is, when I used to plug in my headphones in the front, the speakers would cut out and sound would transfer to the headphones, and when I unplugged my headphones it would continue to play through the speakers as normal. Now, when I plug in my headphones, it plays through both my headphones and speakers simultaneously... so the sound isn't isolated to just my headphones.
So before I unplugged everything to clean my PC, I used to be able to have my music coming through the speakers and when I needed to swap to headphones, I could plug my audio jack into the front panel and the speakers would cut off and sound would play through only my headphones - then once they were removed, sound would get back to playing on the speakers.
Now, when I plug in my headphones on the front panel, it plays through both my headphones AND my speakers at the same time. I tested the rear jacks and found that if I don't have the speakers at the back plugged in, the front panel jack doesn't work at all, so I need the speakers to be plugged into the back whilst my headphones are in to even get the front panel audio jack to work.
I appreciate any help, I just can't understand why something would change within a matter of 20 minutes of me cleaning my PC out.
My audio playback is set to "Device > Speakers" as it always has been, and when I plug my headphones in, it doesn't (and has never) said "headphones" - it just used to play through the "Device > Speakers" (only it must have thought that the speakers was my headphones).
EDIT: I'm not sure if this is in the correct place, apologies I'm still quite new to forums!
