    Hello all,

    I have my Tivo Series 3 HD box connected to my LG using the HDMI interface. This works great except I get some pretty annoying popping sounds coming over the TV. So I connected the digital Fiber from the Tivo to the Stereo Receiver - no pops or crackles!! (unfortunately no Tivo sounds either which is weird...)

    Is there an issue with HDMI on the Series 3? I love the picture and sound quality but hate this random popping and squeaking noise coming from the HDMI audio :(

    No problem from my boxes on HDMI. Did you try another HDMI cable to rule out a problem with the cable?

    This was happening to me last night. First time I had heard it. It seemed to stop after a while, or I just got used to it. I'll see if I hear anything tonight.

    How long has yours been lasting?

    I've only had the Tivo box for about a week and I noticed it right off the bat.... this is the HDMI cable that came with the Tivo... I have another one so I'll try that and let you know what I find....

    I have an LG TV set and haven't had that issue. I did have an issue with the TV set not passing the HDMI audio without a power cycle, though. When I added an HDMI switch into the mix, that problem was solved.

    My TV set outputs optical audio to my receiver from its various inputs. I don't use the internal speakers.

    If using HDMI directly to your TV, go to Settings -> Audio -> PCM. That should eliminate the pops.

    Pops occur on some TVs when audio is set to Dolby Digital 5.1. The overwhelming majority of HDTVs cannot handle a Dolby Digital signal. The Tivo is supposed to detect that your display cannot accept DD, and send PCM instead, but that doesn't always work correctly [with some TVs], and pops are the result.
