Hi. My nephew was playing on my computer, and when he got off of it, I discovered I had a problem. Whenever I access the Internet, the additional base speaker of a 3-speaker setup makes a noise similar to a Geiger counter. I've attempted restoration, changing the Sigma Intel studio settings, and looking for the sound for this noise with no results. Unfortunately, this nephew is 6 years old and thinks that he did nothing wrong. This is a Windows-XP system, and any advice for tracking down this problem and resolving it will definitely be helpful. Thanks in advance. Ted VICUG-L is the Visually Impaired Computer User Group List.
