Hi List. I've got a small BT speaker that was working perfectly until this morning. It has now started omitting, what I can only describe as an electronic pulsing noise, every second, regular as clockwork! I've tried moving it away from any possible electrical interference and tried it with a 4th and 5th Gen Touch as well as an iPhone 5, the electronic pulsing remains. Oh, and the speaker has been tried on and off charge. Does anyone with more experience than myself recognise this kind of BT speaker behaviour? Is this a sign that something has gone wrong and that it may be time to start looking for a new speaker? Darran
