    I cannot explain or figure out what is happening.....here's my setup:

    Comcast Cable
    Roamio Plus HDMI into Yamaha Receiver HDMI into Samsung TV
    Roamio Basic HDMI into Samsung TV

    Recorded MARVEL the other night on the Plus. During the show, there were times where the audio would cut out and back in. Note, I've seen this before mainly on ABC shows in the past. It's real easy to see/hear the cutout because it's going through the receiver. Definite audio drop and the lights go out on the receiver.

    There was a specific 20 second block of the show where there were multiple dropouts. Here's where it gets weird.....I can, not every time, but I can back 8 and get either the dropouts to not re-appear, or be more/less during the same time. So during a 5 second block.....I might hear 2 quick dropouts.....back 8 and next time I might hear 3, or none.

    Here's what I did to test things and why I'm baffled:

    - swapped with a new HDMI cable between the Tivo and Receiver (still dropouts)
    - swapped with a new HDMI cable between Receiver and TV (still dropouts)
    - bypassed the receiver and used new HDMI from Tivo to TV (still dropouts although they are harder to hear)
    - played the show on the Basic over the network (ethernet) (still dropouts)
    - transferred the show to PC and used DSD to make it an MPG (can't hear any dropouts on the PC)

    The things that are puzzling are

    - if the dropouts where recorded, then they should occur every time played in the same spot no?
    - since they don't occur exactly the same each time, I thought it was equipment related
    - but if it's equipment, why would I still hear them on the Basic playing over the network

    Any help or ideas would be greatly appreciated.

    Just an update, saw the dropouts on a recording of the Tonight Show, so it's not just ABC. Again, I was able to rewind and have the dropout not happen.

    I have had the same issue with my Roamio Plus the sound gets warbled and I can back it up a few seconds and the sound clears up.

    I get one every few hours. I blame it on a crappy DD 5.1 hardware/software. They never happen when viewing DD 2.0 or DD EX or when watching a streaming movie on Amazon (which is DD+ 5.1). Just as an experiment, drop to PCM for a day to see if they disappear.

    So would it be hardware even when in home streaming to my other Tivo? Which hardware at that point....the Plus (where it's coming from) or the Basic where it's playing?

    My Dad mentioned he's been seeing more and more with his Basic.

    I thought the problem was coming from the originator (either Charter, or the station) since it doesn't happen every day, and there are long periods between the times it happens. My AVR is a Denon.

    I thought so too, until I rewound and saw that it changes on playback.

    I agree. Sometime is so quick that the LEDs on my AVR don't even blink. Sometimes it's just long enough to make them blink. I watched a lot of older shows on the CW for a while that were DD 2.0 and never had a dropout. While it's possible this is a rare item, this is not the first time it has been a topic either.

    This summer I spent many hours listening to playback on headphones, which are PCM, and never heard a dropout.

    That's where I notice it most.....being hooked up through a receiver, it usually makes the cutout more noticeable. When I bypassed the receiver, I had to really pay attention to notice it in most cases.

    I recently started having audio dropouts too. My AVR shows the DD stream disappearing briefly. I'm guessing there is a problem with recent software update. I hope Tivo will fix it soon as it is really annoying.

    First, you should switch to PCM for a day to eliminate hardware. Second, it may be worse starting with 20.5.2, but I've seen it for a year or more. I started seeing it on my Mini with 20.5.2, but I'm not sure why. If you have a drop, then rewind, and replay doesn't have it, it's not from your content feed, it's from the TiVo output. Or so I would speculate.

    So last night's Fresh off the Boat had a ton of audio glitches early on. Rewinding didn't change anything this time and when I switch to PCM.....it actually got worse. Guessing this was the feed or signal this time.

    TIVO is aware of the issue and are working on a resolve.

    Interesting. Is this from a tech support ticket you have open?

    Spoke to csr today and was told this is a problem with signal from OTA being to low TIVO tuners should be in the 80 plus signal strength was told to try getting amp to see if fixes issue. They also said it could be hdmi cables.

    So that wouldn't be my issue since I'm cable and the signal is 98-100%.

    It's IMPOSSIBLE for a Roamio doing OTA (antenna) to get a signal level higher than 72 on any channel! At least so far, not sure if a newer firmware will ever fix this.

    That's been hashed out in another thread, and absolutely proven. If the Tivo CSR told you you have to get over 80 on an antenna signal, he's full of *****. He's quoting cable signal levels, NOT OTA.

    That is what I told him, and when you check the signal on the channel to see the strength it is higher. Sometimes I get a 80 plus but in a different screen it shows max 72, confusing, if you do a channel scan I see higher numbers.

    When viewing the signal with Settings, Account & System Info, TiVo box Diagnostics you see it after the AGC circuit has settled down the signal. Use the Settings, Channels, Signal Strength test and you will see a peak then it settles on 72.

    The diags are broken or at least not to be trusted.
