I have a problem with a cable docking station in a boardroom where the audio has inherent buzz when the VGA and audio flylead is connected to the laptop. Most times it is the laptop power supply when plugged in that creates this issue, however this time it is not the case. We have tried different notebooks and flyleads etc.
Would a small isolation transformer near the docking station be a solution to "cure" this issue and if so how do I implement it?
Thanks for the help!
