I was cleaning my PC and for some reason my Pc didn't boot after the cleaning, found out the graphics card fan used to spin for 3-4 seconds...then stop and then used to start spinning again and used to do this over and over. Got that to fix by re inserting my RAM sticks a couple of time but ever since the PC started working again the audio jacks (3.5 mm ones) have stopped working. I re inserted the pic connecting the front jacks to the motherboard, still didnt work. I reinstalled the RealTek drivers and tried many different solutions I found online such as disbaling front jack from the realtek settings and stuff. One more thing that i noticed is that i can no longer see the small "x" near the sound icon in the taskbar when i dont have any headphones/speakers connected, it always shows the volume setting unlike before.
