Deafening speaker error??
Every randomly, my son is playing Minecraft on the iMac "just mining blocks" when the speakers of the computer blare deafeningly loudly static. The only way to stop it is to unplug the computer. I suspect it may have something to do with my laundry day. I fold clothes on the kitchen table, which is where the iMac also sits. No laundry touches the computer, but could static be traveling that somehow triggers the speakers to do this? The volume of the computer is always low (below three clicks) when this happens. I also wasn't actually folding when it happened the last time. The clothes were sitting on the table though. Any ideas why this is happening, or fix ideas for it?? TIA!!
iMac, OS X Mavericks (10.9.5)
