ive set it all up correctly, but as soon as my pc logs in i get a high pitch screeching noise. its quite annoying. and now ive placed my speakers where i want them to be ive noticed the volume keeps differing. maybe ive done something worng or just didnt realise this when all the speakers where in one place. and now their spread out i can hear the volume changing.
anyway, i had the same screeching noise with my old crappy 2 set speakers that came with my old pc. so im guessing this is a sound card issue or interference. please help as i dont know whether the pc needs to be taken back. which i dont want to do as ive had it 3 months and already totally personalised it. (ok so not quite brand new but im still proud of it )
