Question
When not in use my Arc occasionally makes random noises
Just recently my Arc when not in use suddenly emits random noises, sort of like popping sounds. It does this quite loudly for around 10 seconds then stops. Thsi is noise happens randomly. Some times 2 or 3 times a day, sometimes once a day and sometimes with a couple of days gap. The first time this happened on first use after the noise the volume on switch on was extremely loud. Since then the volume is always much louder than at switch off when used after the sounds. Any idea what is happening.
