Hi all
Got some monitor speakers and an external sound card this morning (unfortunately not for me). Maybe you guys have some insight.
Problem is that there is interference coming from the boy's laptop's USB connectors (Toshiba tablet). If I listen closely, the interference, which comes from the left speaker, seems to be in "harmony" with what I think is the CPU making noises. The interference also sounds the same on the speaker and when I listen closely to the laptop.
Grounding is good, on a solid surface. PSUs and sources of interference are well away. The interference is amplified when the laptop's PSU is connected. The interference stops when USB is unplugged.
The laptop is still under warranty, unfortunately bought in Australia though (will look into possible international warranty). So I suppose it could go back for a motherboard swap-out, or perhaps it will always be that a tablet laptop's motherboard is lacking. The other option I am thinking of is to convince the father to buy a desktop PC with a decent motherboard and 19/22" monitor, which will definitely be better suited for producing music.
What do you guys think?
TIA.
