    I am experiencing the same thing on an S3, and a neighbor friend of mine is too. We both have Yamaha A/V amps.

    Is TiVo ever going to recognize this problem and do something about it?

    Hi,
    Can someone explain how to change the audio out from DD to PCM? Is there a specific Tivo setting for this and where? Wouldn't that change the audio from Digital Surround to just plain old stereo?
    Thanks in advance,
    Steve

    Sorry i fthis has already been posted but I'd add my observation from tonight.

    I was watching a buffered show (nearly real-time) with drops. When I rewound a good play in the ball-game that exhibited audio drops the first time, the drops were NOT there on replay.

    I have the exact same issue. Has someone contacted Tivo as to whether they acknowledge this and plan to address it?
    Thanks,
    Steve

    TiVo has no "real time", its all from the hard disk, just tune a non TiVo TV to the same channel and you will have a 1 or so second delay between the real live TV and the TiVo connected TV. I know that this information does directly address your audio problem.

    Uh, I know there is no realtime and my post never said there was.

    My point was that the audio dropouts were not necessarily embedded in the recording because when I replay the same clip with the dropout it was not there the second time.

    ah30k,
    Did this happen during the NBA Finals on ABCHD? If so, I think this is a problem with ABC's national HD feed. I'm getting audio drops with the buffer (10 seconds behind real-time or whatever you want to call it with everything being buffered). Others I know of are having drops on this channel (not using a Tivo).

    Did not watch the finals. I was watching the local baseball team on a local affiliate in HD. But the dropouts happen on a variety of channels and shows. And when I replay, they are not there.

    OK; I got what you are saying now. That is typically the same problem that I am generally seeing -- audio dropouts on live , but not there when I replay it. I misread what you wrote. What I was seeing last night while watching the NBA Finals was dropouts that were still there when I would rewind, which was completely different from what I had been experiencing.

    Here's an interesting find. I was rebooting my TiVo this evening, and I actually had a Dolby Digital dropout during the THX screen with the cool sound effect. This can't possibly be related to the hard drive, signal quality, or cablecard, or to any broadcast network in particular.

    I wonder if I just run the THX loop several times if I can reproduce that. What is the easteregg for that? TiVo-0 or something?

    I have had this problem with my tivo series 3 (HD) for a while. I am direct audio connected via rca to my tv and using component video to the tv. No stereo.

    hitting pause for a second and hitting play seems to make it go away. I can also fast forward to the live stream and it goes away only after hitting pause for a sec.. Is my hard drive going?

    on almost every channel change from one DD channel to another, the optical fed audio triggers an "overload" light on my denon receiver and audio stops until the receiver is reset. sometimes the audio lock up clears with a press of tivo "rew" or "ff." i promised my wife tivo hd would be really easy to use and now she is laughing at me! is this a denon or tivo issue?

    I'd say it's Tivo. I've had the same issue with S3 with 3 different AV receivers (2 by Sony and 1 by Kenwood) with the Dolby Digital dropping out.

    Lucily, my receivers just drop out of digital and pick it back up again on their own, but it's very annoying when it happens in the middle of a show on live tv or in a recorded program.

    I should also mention that I've now had 3 series 3's and they have all done exactly the same thing.

    I'd say it was Tivo. I'd also have to say (especially with the 9.3a fiasco) that I am extremely underwhelmed at the Tivo Series 3's performance.

    I paid about $800 for it when it came out - incredibly overpriced for something with so many bugs, IMHO.

    same thing happens to me. i send bitstream to my Onkyo 705. sometimes after i fast forward and then hit play, only one or two of the channels come through - the vocal track may be missing but you can still hear the music. pause and play usually fixes it. but i'm also getting a lot of the "puffing" - loss of sound for a second or two and a "thud" from the receiver since there is a stream hitting and losing. i'm getting a bit sick of it. why can't the TivoHD send a solid signal? all of my channels are 95% or more.

    I was having some DD loss when going from the Tivo Menu/Recorded programs to a Live program in DD (daily). To fix it, I'd have to switch to a channel without digital sound and switch back and it would kick in. In DD to PCM mode it would never happen. I swore it was the receiver screwing up until I recently changed cable co's/cards (from Moto to SA) and it hasn't happened for about a month now.

    i'd rather not run PCM since DD sounds so much better, and i have all the equipment to do it. so i just want it to work :(

    The fix was to purchse a new denon receiver (2308ci - $700), which has better decoding of changing audio signal input and does not give the errors caused by Tivo audio format changes when selecting DD output. A disappointing extra expense, but the TiVo DD audio now works for me.

    Now that they have fixed the freezing problem, does anyone think they will get around to fixing the audio dropout glitch?
