In a previous post, it was mentioned that a buzzing sound was heard while pausing the DVR. I have that issue, but in addition, not only does my audio buzz while pausing the DVR, it also buzzes while pausing live TV. Also, I get this same buzz coming through the speakers of my TV. I just purchased a 70" Sony Bravia. In thinking the problem originated from the Cisco box, Cox came out 3 times and swapped out the same box. The last swap was with a new box, not a refurbished box. Problem did not get corrected. I returned my TV, and exchanged it for another, same model and brand. Same problem occurs. This only occurs using the HDMI cable from the Cisco to the TV. I've swapped out different HDMI cables, and also tried different HDMI inputs on my TV. Problem still exists. I also have a home theater system. If I use an optical audio cable from the TV to the AV receiver, the problem still occurs. However, if I connect an optical cable from the Cisco box directly to my AV receiver, the problem goes away. Most of the time, I only use the audio coming from my TV set, and, save the home theater for Bluray or football games. I'm thinking this is a software glitch with the Cisco, and hoping a firmware and/or software upgrade is going to cure this problem. Anybody else having this same issue? Any workaround?
