Hi can someone help me out here. When I connect my den on box to my laptop via usb there is a lot of static/hiss in the background, has anyone else experienced this and if so how do I get rid of it. I’ve got everything set up correct and my 1210s are working fine when plugged in as normal. The sound disappears when I unplug it so it’s definitely the usb or the dennon box.

Thanks

I don’t know if this is relevant, but it was for my Yamaha speakers, do you have a Wifi router/repeater near to it? It could be that feeding through the interference into the box

Does the bad sound go away if the laptop is run on batteries and with its power cable unplugged?
