    I have the same problem with the audio but it occurs when switching between any HD broadcast from DTV or any digital OTA station. Switching between normal DTV channels doesn't seem to be a problem. I've found that disconnecting the Toslink input and then reconnecting it will usually restore the audio. I've also tried using an optical to coax converter to see if it made any difference but the problem still persists. Switching inputs on my preamp/processor and back doesn't restore the audio either.

    I agree with MoviegoerMan, it appears to be a timing issue. There seems to be a slight audio pause between the time when you switch to a DD5.1 audio stream (or press Plan from fast forward). The pause seems to be designed to allow the audio switching to complete before passing the audio onto the receiver. For some reason, the pause either is missing, or isn't long enough, in some cases, which results in audio being sent to the receiver in the improper format, which results in the loud, scary digital blast that shuts down the receiver's audio protection circuits.

    If the Toslink cable is hard to get to, you might try simply switching to a different audio input and back--this resets the circuit on my receiver.

    It is the only bug I've had with the Tivo that bothers me. It's still way better than my Dish 921, but I wished they would address the issue and fix it. The quicker fix is to find someone who is using an a/v receiver that works around the Tivo issue by filtering the bad packets, then go buy that one. Remember, I'm not saying the cheapest fix.

    Yeah the Denon 3805 does not have this problem so I was thinking of purchasing the 1k amp. I decided not to because I didn't feel the upgrade was worth it. Its up to D* to take care of their problems.

    I have the same problem with statis pop. When I reported it to D* the instructed me to replace the unit. I did, and the new unit has the same problem. When I reported it the acknowledged it as a known problem and would track it.

    Thanks for the instructions.

    Having the same issue and I think Movie man has it figured out.
    I seriously doubt any of the A/V mfg's are going to take "ownership" of this (I have a Pio 49TXi)---This will have to be addressed by D*
    Does anyone think there can even be a download software fix for this?
    Seems like a firmware up date is needed---IF this is correct--how would D* administer this? (over the phone line?).
    I wouldn't look for them to pull everybody's box for an upgrade--way too expensive.
    Can they activate the USB's remotely? Could this be an input interface for an upgrade? (if so, how would that be done?)

    I agree it's annoying. I'm surprised, though, to realize that we aren't talking about the same thing. I can FF/REW/Trick Play, whatever all day and never have this happen.

    It ONLY happens to me when I start playing back a pre-recorded show with a DD soundtrack (like, say, Lost), or I switch from a non-DD channel to a DD channel.

    Once past that first "burp" (and yes, I have to switch inputs), it never happens again unless I start a different show or something.

    I wonder why that's different?

    (For what it's worth, I agree SO much that it's annoying that I switched back to PCM mode last night, even though I'm not having the problem as often as you).

    Ereth:

    Yes, it is curious how it manifests itself differently for us. My theory is that the TiVo is sending a mal-formed audio signal to the AV system, and different AV systems react differently.

    You can get it to happen using the Trick Play functionality (FF/RR/Advance/Skip, etc). You have to find a program that has the commercials recorded in PCM and the DD5.1 recorded for the show. If you skip into the commercial, the audio will switch to PCM. This would be the same as changing to a PCM channel as far as your a/v receiver is concerned. You can get the "static pop" sound to occur when you skip from the PCM commercial to the DD 5.1 show. It's very consistent if you have the recorded source to test it.

    It is easier to reproduce it LIVE if you find two channels. One channel that is PCM and the other that is DD5.1. Then just use the Enter/Return button on the far bottom right of the remote to keep swapping the channels. You will hear the "static pop" everytime you go from PCM to DD5.1, but you won't hear it from DD5.1 to PCM.

    My guess is the Tivo is spitting out an different DD format that some of our receivers can't process. Instead, they process the DD packets as PCM and that's when you here the POP.

    Pio 49txi---vs switching inputs--I can go from a DD channel to a PCM channel then back to the DD one and that fixes it 99% of the time.
    This seems easier to me than switching inputs
    The "pop" occurs on live viewing just as much as on recorded

    I called d* to complain about this issue again and of course they have never heard of this. I am just about to put this thing up on ebay.

    Had hoped that the new "E" software download would have addressed the static pop issue, but no luck--it's still there. <sigh>

    They can't even create a successful upgrade without screwing up the stb. I lost my ota meter due to E. I doubt that this will ever be addressed.

    I am having problems with my HR10-250 HDTV DVR and my Pioneer Elite receiver. Whenever I go to a DD channel I get a gargeled sound and then no sound at all. I read the other posts and it sounds like other people are having the same problem with Pioneer and also B&K. What we need to do is call Directv's Tier 2 HD Specialist department @ 888-713-7772 and log a complaint with them. They told me I was the first one to call however after reading this web site I see that there are more people who have the same problem too. They told me they will not fix the problem until a few people call with it.

    EVERYBODY CALL SO WE ALL CAN WATCH AND LISTEN TO THE TV THE WAY IT IS SUPPOSED TO BE.

    Also post a message when you are done calling them so the tivo community knows how many people called Directv.

    Thanks

    P.S. My exact receiver is the 49TX

    They tell everyone they were the first to call. I've lost track of how many times I have spoken with tier 2 support on this issue, only to be told everytime they have never heard of it before.

    The bottom line is, until the reproduce the problem (which won't happen b/c they aren't going to buy a high end receiver for their test lab) they wont acknowledge it is a problem.

    Now who's going to buy them a Pioneer Elite 49txi?

    Where are they located? One of the many times I have called, I talked to someone in FL. If they are within 100 Miles of Me (Huntsville, AL) I will gladly make a trek. I get so tired of having to toggle between DD and Pro Logic to listen to a recorded movie. This is getting ridiculous, I know I have caleed them 5 times, and have gotten 2 people to admit their is a problem.
