I recently bit the bullet and decided to shell out copius amounts of money upgrading my aging computer. Aside from a minor hiccup with keyboard not being recognised during the windows setup all went well. That was, of course, up until the point I decided to test out my speakers.
It would appear that there is some very odd noise being generated somewhere, and I am currently inclined to believe that this is a software issue.
The speakers work fine when connected to other audio equipment, so am confident the speakers are not at fault. I was originally using the on board realtek HD audio however I switched to my old Creative X-Fi sound card when I noticed the problem, but still it persists.
I've muted all the input sources that I can find. Uninstalled and re-installed all the drivers. Windows 7 is up to date. I cannot think of anything else that might casue this. The noise isn't your usual buzz, it seems vary in intensity ever few seconds, and frankly just sounds odd.
Does anyone have any idea what might cause this? Are there any known sound issues with Windows 7?
