To make a long story short, a ground loop is when an electric circuit is made between different audio device that are connected to the same electric power grid with badly grounded connections.
This is an electrical problem generating noise, nothing to do with software. To test if this is the origin of your problem, try to use the devices unplugged from the electrical grid and check if the noise still there Sincerely, Giovanni Maruzzelli ========================================= www.celliax.org via Pierlombardo 9, 20135 Milano Italy gmaruzz at celliax dot org Cell : +39-347-2665618 Fax : +39-02-87390039 2009/4/1 Stromin Normin <[email protected]>: > Cheers for the replies.
