    You say that the audio breakup was recorded, but then say hitting pause, then play caused it to "come back". If it was recorded, it would drop out at the same spot every time and not "come back" no matter what you did. Please clarify.

    Before the stations when to full power last year, some of them were prone to frequent audio dropouts even though picture didn't seem to be disrupted. Perhaps the occasional dropped bit doesn't disrupt MPEG as much as DD.

    It became much better with a stronger, less variable signal. The signal stregth meters on digital tuners do measure received power so much signal quality. Stick a splitter on the antenna cable and the signal values usually drop relatively little.

    I said sometimes the audio went away. As in it went silent. This is separate of the audio/video breakup.

    So . .


    Audio/Video Breakup.
    Cleared the guide
    Perfect video with no audio.

    Pressing Pause then play brought back the audio.

    Rewinding and playing showed the audio/video breakup.

    Sounds pretty close to my situation....

    I used guide and then search function.... returned to channel and found no sound. Channel up channel up channel down channel down and audio came back. I didnt rewind to check buffer but I will next time!!!

    cyuhoga,

    I have the exact same problem and described it here in the 2nd post

    http://www.tivocommunity.com/tivo-vb/showthread.php?t=316954&highlight=rehr0001

    I can replicate it over and over again by switching between an analog cable station and a digital station (OTA or digital cable). Everytime I go from digital to anaolg, the sound is gone. To get it back, all I have to do is change dsp modes (dd to logic7, dd w/thx, etc). The only way to avoid it is to use DD to PCM in the audio setting (which will eliminate your 5.1 sound). What kind of receiver do you have?

    MisterUCLA,

    Is the audio disappearing from both the TV output AND the receiver or just one of the two? My issue is with both outputs disappearing.

    Well... ive been running an experiment. Ive been getting the momentary audio drops while watching recoreded shows and then with live football pregame. I started the 8300 and the S3 both on the pregame. I just had a 1 sec audio dropout during the manning breakfast commercial. I went to the 8300 and backed up and there was NO audio burp at all....

    Watching some recorded HD and see these glitches every 5-10 mins. audio stops and then restarts with some image pixilation. Also watched some SD recordings and also had lots of little audio drops but didnt see any video impacts.

    Sucks...

    OK, I'm getting more concerned now. I was watching Prison Break and was getting audio dropouts every few seconds for awhile. It did not repeat later when I played back the buffer and it was not occurring on my Motorola FIOS PVR. Before I had only seen it when in the guide. Me thinks there's an issue here. :(

    Oh yes, signal strength on this OTA channel was 92.

    If the audio dropouts continue when I get my CCs installed (just using OTA HD now), I'll return the S3 while still in my 30 day return period.

    Similar issue here -- for me it seems to be live HD broadcasts.

    On some occasions, when watching a live HD broadcast the audio will drop every few seconds or so.

    Pressing pause, waiting a couple of seconds, and then pressing play (thus watching the broadcast a few seconds behind) clears up the problem.

    Happy to have found a workaround, but not really acceptable for an $800 product.

    Hopefully this can be fixed in the upcoming software update!

    Probably a dumb suggestion, but make sure your optical connections are clean and well-seated. I used to have audio dropouts all the time with an old cable box and isolated the problem to a bad cable.

    I sure hope my receiver's optical input works. I haven't used it in years since almost everything seems to use the cheaper coax digital audio connections. Maybe when I get my S3 box in the mail I'll have an excuse to upgrade my whole system :)

    I can't always reproduce it either. In fact, I haven't seen it happen on its own in quite a while. But I can occasionally make it happen. I'm guessing that it has to do with how much work TiVo is doing behind the scenes. When I can make it happen, it's extremely clear that it's happening as a result of scrolling through the guide, but scrolling through the guide doesn't always make it happen.

    In my case, the problem is happening with the HDMI cable -- have tried multiple cables with the same result. It's definitely the Tivo.

    In my case I used the same cable that has been giving me flawless audio and once it's hooked up to the S3, I get dropouts. I put that same cable back to my Motorola box and the dropouts disappear. So at least in my case it's clearly the S3.

    Yes, this is when it happens to me--live HD broadcasts.
