I was in a system just the other day and I heard clicking and crackling, that sounded almost insect like. I actually thought there was a problem with my sound card so to check I dropped out of SC and it immediately stopped. Regretted doing that immediately :/ Couldn't get it back
Ditto....I noticed the same sound effects & also thought that my sound card was on the blink. It went when I jumped to another system & I haven't heard it since.
But as Iv only been keeping a small amount of interest in Jaques, I wouldn't be investigating stuff like that.
