Speaker - General Discussion

[FlyingV]

Hi

I've had some logitech speakers for a while (unsure of what they are - they are some kind of ipod dock portable speakers) and I haven't really used them for a while. I plugged them in today, and they sound great, but when no sound is coming from my computer, it starts to buzz.

If I turn off any noise coming from my computer, about 5 seconds after, a persistent buzzing will occur. Weirdly, this only occurs with the charger in - taking it out prevents any of this noise, but the speakers turn off after around 20 seconds to save power.

Any help would be great!
