I updated from XP SP3 to Windows 7 Ultimate, making no changes to hardware/wiring, simply formatting my hard drive and giving it a fresh install of Windows 7. I allowed the updates to find all my drivers, and it found a driver for my sound card. However, no matter how I fiddle with the settings for it, there is no sound coming out of the front right speaker. I uninstalled the drivers and installed the latest official one I could find from the Creative website, still no luck. I found an unofficial driver on the Creative forums and tried that, with exactly the same results - all speakers work as they should with only the front right not working. I do not believe there is a hardware problem as I did not touch any of the hardware during installation, and the power/volume control is on the front right speaker and is working fine. I can even hear a really quiet hiss coming from the speaker, but no proper sound. If anyone has any insight into this problem I would be glad to hear it.
