    Boy I'm glad I have a cheap(er) Kenwood from around 2000-2001 instead of an expensive Denon or Onkyo receiver. My interuption during pause & channel change is between a half second and a second.

    The real solution would be for TiVo to output a silent uninterupted DD stream during these opperations. That's what DVD players do.

    Using a Harman Kardon hooked up toa Tivo HD via TOSLINK and experiencing the same problem. Have the latest update. I've noticed that it'll happen only on DD as well, and while its sportatic, it's more likely to happen during FF or Pause functions.

    FWIW, I'm currently using the optical output from my TV because I didn't have enough cables at the time to wire everything straight to the receiver and I don't have this problem at all. Of course I don't have 5.1 sound either, but at least its clean. I'll have to try the cable from the back of the tivo and see what I get...

    TV is a Samsung FP-T5084.

    Add me to the list. TivoHD with 2 motorola S CCs feeding a Harman Kardon 635 (I think) via Toslink.

    i'm in too, onkyo 605, tivoHD via HDMI.
    i'm marking this thread to check back from time to time to see if a fix comes around, maybe a new tivo software update (9.3?) will take care of it.

    Anyone notice whether this only happens on certain channels? As far as I can tell it only happens for me on ABC, channel 6-1 OTA in Philly. I haven't seen it happen on any of the other Dolby Digital feeds.

    I've seen (actually heard) it happen on a bunch of cable channels. I have witnessed it on the following channels over the past two weeks: Fox News (SD), ESPN HD, KDKAHD (CBS), sci-fi, sci-fiHD, Nat Geo HD, ESPN2 HD, WTAEHD (ABC), and WTOVHD (NBC).

    Time to bring this one back to the top...

    I ran the optical cable to the tivo about a week ago and I've seen a little of what some of you are complaining about but I wouldn't say it's a big enough problem for me at least to complain very loudly. It seems like usually the drop is sound is associated with a signal problem most of the time. I notice a few random pixels on the picture flash out at the same time I have a break in sound.

    On a good note though, I had no idea so many programs were broadcast in DD. I'm in hog heaven!

    It's even more disappointing now though when I have to go to a standard definition program. The picture and the sound suck for me now. :D

    I'm having the same audio drop-out problem. TiVoHD (with Comcast multistream card) --> Onkyo 605. The TiVo guys convinced me that if I just added a 10-db cable signal booster, the problem would likely resolve. Well, $30 later, after a trip to Radioshack to purchase one of these, the problem has returned. Given that many of us are experiencing the same problem, can't we somehow prevail upon TiVo to at least acknowledge that this is a problem that needs their attention?

    This is not a cable signal quality issue if on a replay you do not see the audio dropout again. That is what I observe. I wonder if 9.3a will help...

    Funny, that was a known and never fixed issue with the DirecTiVos. Random audio dropouts over SPDIF. It happened pretty regularly to me with both of my DirecTiVos and my old Sony receiver. As with what people are reporting here, it's not a signal issue most of the time, as you can skip back and hear the correct audio.

    Oddly, I don't have an issue with my S3 and my Onkyo TX-SR605 over HDMI. I did have a problem with my Sony receiver over optical for a while, until I realized that my optical cable was going bad. Yes, they can be broken such that they cause intermittent dropouts.

    What's really odd is that my Onkyo seems not to unlock from the DD stream like my old receiver did. Perhaps the S3 treats the HDMI and optical connections differently.

    Interesting. My Onkyo 605 "unlocks" from the DD stream on every button click. It is connected via 18-inch HDMI from my THD. I get identical behavior if I get audio via optical. I believe it happens only on DD5.1 for me and not DD2.0.

    Just to report, that 9.3a does NOT fix the problem for me at all.

    I actually think this is beyond just a minor annoyance. Every program has these dropouts at least once every few minutes. Switching to PCM solves it completely, but that is a big pain.

    I hope this gets fixed soon. Oh, and for what its worth, I never had this problem on my DirecTivo using the exact same optical cable and receiver (as some have reported this problem was on that device as well)

    I've seen a bunch of references to Onkyo receivers in this thread so I thought I'd point something out to those who didn't already know. Onkyo has new firmware for the x05 receivers available over at the AVSForum. Look in the Audio Area in the Amps and Receivers (or something to that effect) section. There's threads for each receiver type and a generic Onkyo update thread with the links for each one. It fixes the slow lock ons (and the static/pops associated with them) and the "DTS bomb." I hope this helps.

    Just my 2 cents.. I am having this same issue, and have been having it for about 2 months now. My receiver is a Bose 3-2-1 GS system. I have to switch inputs on the Bose back and forth every time to fix the issue.

    It is so bad for me, that I am at the point where I dont even ff through commercials anymore because as soon as I ff, and hit play again, I have to switch inputs. It is very annoying.

    I am running 9.3a

    The fact that there are varying degrees of this problem kind of make this one a hard one to figure out. It varies from a dropout every few minutes like the above to mine where I get maybe 1 drop out every few hours. If this were strictly a Tivo firmware problem it should be consistent across the platform.

    What are the variables here?

    I had thought 9.3 fixed my issue. I hadn't observed the issue for a couple of days after receiving 9.3. Then last night, it was back with a vengence. I had the Mythbusters marathon on DiscoveryHD on in the background for about 4 hours while I was doing a house project. It started dropping audio approx every 30 minutes. By the time I got sick of it, it was dropping audio about every 2-3 minutes. I rewound it approx. 10 seconds and played it for the next hour from the buffer without another drop.

    OvrrDrive - you're right, there are many variables, a few of which are... receiver brand and model, input source (cable, OTA, FIOS), cable card brand (SA or moto), cable card type (Multistream or single stream), channels, optical or HDMI, hard drive (original, modded, or WD expander), frequency of drops, types of drops.

    My answers to these variables are:
    Receiver brand/model: Onkyo TX-SR605
    Input Source: digital cable - comcast.
    cable cards: moto, (2) single stream
    channels where it occurs: I've experienced it on just about every digital channel, so I don't think there is any ryhme or reason to which channel.
    audio output when drops are experienced : optical and HDMI (I've tried each and experienced drops with each)
    Hard drive: I had with the stock drive. I also still have it with a WD DVR expander added.
    Frequency of drops: varies. After a reboot, it is very infrequent (once an hour or less). As time from reboot increases, it becomes more frequent (as often as once every couple of minutes).
    Types of drops: receiver loses audio signal (indicator on receiver goes out) for a couple of seconds. Drops are not there on the recorded viewing (either on the buffer or when viewing an actual recorded program).

    OK, somewhat similar audio problem here. Didn't have it on 9.2a. Setup:

    Series 3 TiVo HD (9.3a)
    TOSLink to Panasonic XR-25S Receiver

    TiVo recordings with 2.0 audio do not play audio until I switch audio inputs back and forth on my receiver, or turn the receiver off and then back on. Same autio issue whether recording was a local cable feed, or with downloaded TiVocast content. Have to toggle audio receiver inputs, or receiver off-the-on. Again, problem never occured on 9.2a...just appeared on the 9.3a install.

    Audio does not come back on when toggling TiVo DD5.1 to PCM and back.

    Audio does not come back on when toggling TiVo from DD5.1 DTV OTA signal to mono or 2.0 stereo channels.

    Oh, yea, same audio setup as above...never had this problem with the Comcast/Motorola 3412 DVR in two years of use...

    Come on TiVo...television audio has come a long way in the last 20 years...time to catch up! Hopefully they will get this fixed soon...what a major PITA...

    I'm sorry that you're having an issue with your Tivo (I seriously am empathetic); however, your issue doesn't sound as if it's related to the one for which I started this thread. I have informed Tivo of this thread and been led to believe that they are checking it, so I would really like to keep this thread related to my initial post -- those experiencing audio that drops out when watching a live recording, but the problem isn't there when going back on the buffer or for recorded programs. For the situation I am describing, the issue is also resolved when changing audio out from DD to PCM.

    Thanks in advance for your understanding.

    So in other words, you've totally diagnosed your own audio issue, and mine, and came to the conclusion that it isn't related to yours. Tell me how you came to that conclusion. Give me a break thread cop :rolleyes:

    Maybe my post offers additional data points to TiVo, maybe not. But I'd like them to determine that.
