Hello - I looked around and couldn't find anything - so here goes: I have a TiVo series 3, using Comcast Cable Cards, connected to a Sony Bravia via HDMI. My problem is that when scenes feature music with a lot of bass, the audio becomes severely compressed and talking becomes almost inaudible. Examples: "The Killing" frequently features music that causes a pulsing like quality as the effect kicks in and turns off; there was a scene in the Social Network at a loud club that was completely unintelligible due to this. The other key point to this problem is that it is relatively new. I've had this setup for maybe 3+ years. The audio problem only started maybe within the last 6 months. Given that it is just started, the only guess I have is that Comcast changed something about their audio, and maybe the audio sounds fine through their boxes, but not through the cablecard-tivo-tv setup. But I have no idea how to go about debugging the problem or proving what is wrong. Any advice? I think I'm going to try not using HDMI, and switch to a different output format, but its a hassle to rewire everything. But I'm pretty frustrated now so I guess that's what I have to do. Thanks for your help.
