So recently, I had an issue with my on-board audio (Motherboard: DH61WW). For some reason, the audio jacks wouldn't work (both front and back), and I also tried putting an X-Fi Soundblaster XTremeMusic into my PCI slot but it wouldn't work there either. The solution I've come up is a DVI to HDMI cable to my monitor and playing the sound through my monitor. I've been through all the loops trying to fix my on-board sound (I've reinstalled windows and all my drivers, reset my BIOS settings, tried all the audio ports on my computer...). I'm pretty sure it's a hardware issue.
When I plug in my speakers to the audio jack, my RealTek audio drivers recognize that a device has been plugged in (even recognizing that it's on the back port) and asks if it is speakers or headphones. However no sound is produced when I do a sound test on the volume bar. The problem is not my speakers, I tested them with some music on my phone.
