I have been using a pair of external ZoltriXound speakers attached to my Toshiba laptop for the last 4 years. Recently I moved to a different area of the city & am now faintly picking up what sounds like a radio channel, when I turn them on. Toshibaadvises it is not the sound card. I have tried wiring to a separate room & changing the speaker wires & unplugging the remote phone attached to the same power source to no avail.
I am not sure if it is the quality of the speakers, if there is a shortwave or satellite dish nearby that may be affecting the reception.
To date no one has heard of this problem & a search on your database doesn’t bring this specific topic up, although it does talk about interference. (I tried the suggestions in that article.)
Any advice is appreciated.
