Since I got the cable cards installed, I haven't had audio on four digital channels. The video is fine, but there is no sound. Before the S3, I had a digital cable box that didn't have this problem on those channels. I called TiVo support first and was told that it sounds like a problem with my cable provider. I had a tech from Adelphia come out today to look at the problem and he had no clue. He hooked up a digital cable box and confirmed that there was sound on those four channels. Since there's no sound on those channels with EITHER cable card, he concluded that it's not a problem with the cards. He basically said to call TiVo. Now what?
