    I doubt calls to support will do much good. They KNOW this is an issue. (and they are aware of this thread)

    Still no more problems now that I cleared up my over the air antenna issue.

    Maybe my problem was unique.

    Not to mention they'll just deny there is a problem that 25 or 30 resets won't take care of. It's only been a month and a half, it should be cleared up soon.

    It turns out DirecTV is aware of the problem. Here are the details:

    The bottom line is that this problem happens due to errors in the broadcaster's AC3 digital audio data stream, and those errors cause DirecTV's MPEG4 encoders to "brrrrp". So the problem truly lies on both ends .... the broadcasters need to improve their equipment to eliminate those AC3 audio errors, and DirecTV should improve their equipment to be less susceptible to these audio errors.

    Posted by user rga8350 ....
    "I work for a local TV station and we have become aware of the "motorboating" of DirecTV audio followed by an audio dropout. Our viewers have complained about it for weeks.

    DirecTV's tech management says the problem is caused when the AC3 encoder at the video source sends out extraneous packets of information. DirecTV's equipment bounces the extraneous packets back and forth several million times in a fraction of a second, causing the "motorboat" ripping sound everyone is complaining about, followed by a short period of no sound. The DirecTV gear detects the error and cuts if off. When the cut-off occurs, that kills the sound for a fraction of a second. Then the sound picks up again. All this happens in less than a second, but it's annoying. We also have anecdotal eports that the errors spoil DVR recordings. I noted three motorboat incidents in just the first three minutes of this weekend's Oklahoma football game.

    These extra packets are errors in the AC3 data stream, and DirecTV's gear appears to be unable to handle them. DirecTV's CSR's have been instructed to tell anyone who complains "We are aware of the problem and are working on it." DirecTV doesn't know why their equipment can't handle AC3 audio errors. They are working on a "band aid" solution, which is a software patch which will remove the "motorboat" buzz and replace it with silence. I don't think subscribers are going to stand still for programming with holes in the audio, so DirecTV has to find a permanent solution.

    Some broadcasters are experimenting with all sorts of fixes including very expensive Dolby audio frame synchronizers, but that is just an experiment and probably won't work. Until DirecTV figures out a way to process out the AC3 errors this problem is going to continue."

    I also have not heard a Brrrrip in a while (I can't remember the last time I heard one), but they have been replaced by the audio dropouts. I am getting the audio dropouts a lot on only the HD channels.
    I had been getting the Brrrrips alot, so I also feel that they are the same problem that has sort of been "fixed".

    I shot them another email today just to rattle their cage a little and believe it or not the "engineering dept" called me. Of course they wanted to do resets and check the wires in the back of the receiver and seemed to be a bit disappointed I had already done that. LOL

    Of course they haven't heard of this problem. Not to mention they have never heard of this forum. Long long silence time and I finally told them if they didn't have any more questions my wife could listen to silence on the phone as well as I could, I was busy.

    She listened to silence for another 10 minutes or so and then they said they were going to transfer her. Another guy comes on the phone and said he didn't know if it would be fixed today or tomorrow but it WOULD be fixed. !rolling

    I swear those people thrive on blowing smoke......

    They did ask for the address to this forum though.

    There is no doubt in my mind calling DirecTV for any technical issue like this is a colossal waste of time. They are never going to have their real engineers speak to the customers directly. I have tried calling them on several issues and always got the reboot answer. They also have denied issues that were much larger than this one which has been the most frustrating part of dealing with DirecTV. What be interesting to know is how does DirecTV pass on the 'real' issues to the folks that can make a difference.

    Does this mean this issue is related to the confirmed issue in LA in this post?

    It's actually San Francisco, but yes.
    One thing to note. I know that in some cities there have been changes to the settings of the DirecTV MPEG-4 encoders that virtually eliminate the "brrrp" events but you get dropouts instead.....

    I've had constant audio drop-out since the last national release. They last from a tenth of a second to two seconds - happen on all channels, including OTA. Never had a problem before this last national release.

    I have dropouts all the time, both live and recorded of course. It is very annoying watching a program and have a dozen dropouts during the 1 hour show.

    I am starting to notice a trend, I don't get very many dropouts on my locals, but SyFy, TNT, USA and FX are constant issues.

    I am getting a lot of audio dropouts on CNN and other channels. Should I be concerned this is causing wear on my Onkyo receiver with my HDMI connection? It makes a lot of clicking noises trying to sync the audio.
