Hi all any help would be appreciated
When my laptop is plugged into my sound system ( crown amp and mixer 4 JBL speakers ) with all power on there is no problem, until I start VDJ, a medium level humm emitts from the speakers it is not noticable when the music plays loud, and seems to stop for a second while a track is loading on a deck A or B this sound does not happen when playing music through the same with winamp etc. I did read about ground loops in another forum and this does not seem to be the problem I am running a Dell with an Audigy Platinum card and my music is stored on an external firewire drive I dont know if this info is related to the problem but it seems to be specific to when VDJ is up and running
Thanks Clay

Does the problem persist if you disconnect the mains and run the laptop on batteries? Try also disconnecting the firewire drive as well, just in case the hum is coming from that... I know this in itself isn't a fix, but might help diagnose the problem... It's a long shot if you say it doesn't cause a hum with winamp, but hey, worth a try nonetheless...

Most laptops will give a hum, when connected to a sound system. The cause is a ground loop problem in the power supply of your laptop. You could test this like djsherz said, to disconnect your power supply from the mains. Search the forum for ground loop. Several threads with good solutions could be found.

I have one and love it. It totally got rid of my problem. You plug your laptop power supply into it. It worked for me. Do not go the two prong power cord plug in method. Its considered unsafe and a fire hazzard.
