Since D* installed 2nd dish for locals 2 weeks ago I have a bleep and blip sound coming from spkrs (sounds like atari pong game). I have switched audio receivers, rerun spkr wires, systematically disconnect other components nothing gets rid of this noise. I have 7 lines, 6 for tv and 1 tivo.Finally I remove all lines from 8 way multiswitch going to receivers in my home after plugging in 1 cable at a time no noises till I connect cables 5 and 6. Directv tech replaced and grounded multiswitch and kept scratching his head and says MAN I CANT FIX THIS ! Will try anything! THANKS RICHIE
