Advertisements I've searched through the forums and haven't seen this issue, so I wanted to ask if anyone has seen it... I just purchased my first Tivo, a Premiere (45H) and it's been almost flawless. I have one issue, there is a high pitched whine in the background of the sound in some channels. On certain channels, it is always there. On other channels it comes and goes. It doesn't seem to happen on internet video (YouTube) or within menus, only on cable. Setup is Tivo connected through HDMI to a Sony XBR6 TV. Some things that I have tried: Switched from Dolby to PCM and back Swapped HDMI Cables Swapped HDMI Ports on TV Tried Composite Cables Tried on Different TV Rebooted too many times to count Changed multiple sound settings on TV (Dynamic, Standard, Surround, etc.) The sound is a bit like what you used to hear on older TV's that you had to tune into or adjust the antenna to clear the distortion. I'm currently connected to basic cable (M-Card should be here tomorrow). I've called Tivo and they are at a loss, I'm hoping that perhaps adding the M-Card will clear things up. I'd rather not deal with replacing the unit through Tivo since it has worked so well so far. Just wondering if anyone has any suggestions? Any assistance is greatly appreciated.
