If anybody can test it and let me know if they have it too, an easy way would be to just call a 1-800 number, such as 1-800-BEST-BUY. I'm curious to see if my speakers are starting to go out.
Once again, the issue is only there while they're making a sound of any kind. If they're quiet, there is no static.
I just noticed it happens in non-speaker mode as well. Maybe it's just the fact that it's a phone call and it's not meant to be crystal clear?
