Operating System: Windows Vista Home Premium Sound: Onboard Realtek (Not sure of the name exactly) Hello, So about a month ago I inserted a WAN Card into my PC and after doing so am having an issue getting sound out of both of my speakers. If I slowly slide my speaker plug into the motherboard it will play out of the left speaker only. Once I slide the plug all the way in, the sound only comes out of the right speaker. I do have front jacks that work fine, but I'm trying to avoid using those as I have a one year old who has learned how to walk and loves to play with things in her reach. Things I've checked: 1. I'm reopened my computer to see if I happened to knock anything loose during my WAN Card installation process. 2. I've checked the balance setting for my speakers. 3. I've plug in a headset to make sure it wasn't a speaker issue. 4. I've ran the "Speaker Setup" wizard offered by the Realtek software multiple times. 5. I've removed the WAN card and tried to use the speakers then. Is there anything missing or am I just out of luck? Thanks!
