Hey all My I-trigue speakers gave up the ghost the other day, so I bought a 2nd hand set of Creative A250 2.1 speakers from ebay for ten quid. These arrived this morning. I unboxed them to discover they were brand new: all the original packing, sticky labels, and box itself untouched. Impressed, I wired them up, plugged them in.... result was appalling. Deep hum as soon as I switched the speakers on by their rotating on/off/vol switch located on the right hand speaker. I have ensured all are correctly connected; checked the volume levels; ensured there is plenty of space between speakers etc to no avail. This kicks off immediately the speakers are switched on at the lowest possible volume. Any suggestions gratefully received. I am running an Alienware X51.
