...Digital Coax Audio to my Bose surround sound. Its cuts out for about 4 seconds every 15 seconds or so. I switched the input from Aux, to Vid1, Vid2 on the Bose and still the same. I did not have this problem when I had it hooked up via optical, but I added a DVR that is taking up the only optical on the back of the Bose...could this be a DVR issue?
