Are there audio issues on Roamio or is it just me?

    I don't have the TiVo sounds turned on and the receiver was working fine with the Elite. I have changed the HDMI cable and I still have the problem. I can try changing the HDMI port on the receiver but I haven't made any changes to it since the Elite was hooked up.

    Could you try hooking the tivo directly to the TV as a test? If you still have the problem, you know its the TiVO, if the problem goes away, its something to do with the receiver.

    The TiVo sounds don't work with DD audio anyway, so any time you do a trick play a tiny bit of silence is introduced. If you are using any sort of auto normalization setting then that bit of silence could confuse the algorithm and cause the effect you describe.

    THX certification means absolutely nothing.
    I am using an optical connection to the Roamio just like on my Premiere and the HD before that. Sound is exactly identical (as one would expect).

    If there is a change, it is something you introduced outside the TiVo or your audio settings are not the same (or your Roamio is just broken, which is the most unlikely case).

    Don't know about the postings about audio volume changing on jumping back in video. I have had my Roamio for weeks and have not had that happen.

    I've experienced similar "symptoms" before which turned out to be an audio cut out of digital audio out to the receiver, but the audio on the TV was enabled at a lower volume so it seemed as though the volume was cut down when really there were 2 audio sources and one was dropping out entirely.

    Haha, hadn't even considered that. I always turn off my TV speakers and use the receiver exclusively, but this makes perfect sense for those who use both.

    I lose sync on my old receiver (hk avr8000) when I'm using DD and switch from live TV to Netflix or other apps. In order to get it back, I have to cycle the digital mode on the receiver to force another handshake and get my audio back. Had this on my series 3, went away on my premiere, and is back on the Roamio. I just set it to PCM and use Logic 7 on my receiver to get it back to "multi-channel" and it still sounds great.

    The sound on the TV is off. I don't have the problem when turning off Dolby in the TiVo's settings so it's definitely something to do with Dolby Digital. I'm working with Margaret on it through e-mail and there has been mention of an audio problem with Netflix (which I haven't used yet on the Roamio). If this problem is related to that one, hopefully the fix for it will fix my issue as well.

    There is absolutely no way TiVo could effect just a single channel of the Dolby stream. It's just not possible with compressed format like AC3. The only thing they might be doing wrong is reporting the wrong format to the receiver via HDMI. Then your reciver could be trying to decode the wrong format and get an error. If it was something similar, but different, like EAC3 it could result in a minor error that only sounded like slight distortion.

    What is the audio problem with Netflix? The only thing I've noticed is when I pause and resume, it takes 1.5 to 2 seconds for the DD+ audio to return. It's not instant but 2 seconds it not a big deal.

    Although I'm curious what it does on the Mini. I need to try that and see if there is a difference.

    EDIT: I see with the Mini the audio comes back slight faster. But only half a second faster. It takes 1 second to 1.5 seconds for the DD+ audio to resume from pausing on the Mini.

    Although it's really not an apples to apples comparison since the Mini in this room is connected to a Sony 2.1 Speaker Bar while my Roamio is connected to a Denon receiver and DVDO DUO.

    EDIT: I found teh thread about it. A long pause causes a longer amount of time for the audio to return. But with my Roamio connected to my Denon receiver and DVDO DUO, it results in the audio taking only 5 seconds. While my Mini connected to the Speaker bar takes several times longer.

    It's a Harmon Kardon/lexicon processing mode that turns 2 channel sound into 5/7 channel sound and does it really well

    Does it work better than Dolby Pro Logic IIx?

    Personal preference, but I definitely think so.

    So it is totally fake, made-up surround? Or is it analog Dolby Pro Logic or something?

    Read here- http://www.avsforum.com/t/1408362/logic7-beats-dolby

    they'll do a much better job than I will. My avr will apply logic 7 over dd, too, and I use it exclusively. Just sounds better to me

    I would think it's similar to DPLIIx which creates up to 7.1 discrete audio from 2 channel audio. Either way that is much better than the Sony 7.1 receiver I had back in 2001 which used DPL(Or was it DPLII?), but I think the back surround channels were mono instead of simulating discrete audio.

    I just know the first 7.1 receiver I had with DPLIIx was a big improvement.

    This is incorrect. DACs (digital audio converters) vary widely in quality. You will absolutely hear the difference between an audiophile-grade DAC and a cheap one.

    I'm also having audio issues with my Roamio, the OP is correct, the sound is off. Coming from an Xbox One, music sounds slightly muffled and compressed, with a far narrower sound-stage. The Spotify service on the Roamio streams at 320kbs (roughly CD quality) whereas Xbox Music is only 190kbs (older MP3 quality)... So if the chipsets were comparable, the Roamio should have the edge. This points to lower-end audio hardware at work within the Roamio.

    Frankly, it may be a deal-breaker for me. I like the all-in-one convenience of the Roamio, but I'm not going to tolerate bad sound when I've spent thousands on ultra high-end speakers and amplifier. Granted, I often listen to vinyl or HD CD's, but I enjoy streaming music services for quick listening and discovering new music.

    I'm using a basic 4-tuner Roamio, perhaps the higher-end models utilize a better chipset for audio. I'll investigate... If the sound is the same, I'll unfortunately have to return the Tivo and continue using the Xbox One with my cable box as an all-in-one interface...

    I realized that my Roamio Pro does not output Dolby Digital audio using the HDMI connection when using the streaming apps like Netflix, Vudu or Amazon. It does work fine and output DD via HDMI when viewing my normal cable shows. Furthermore, for me to get DD output when viewing Netflix, Vudu or Amazon I need to use the Digital Optical port. I have called Tivo support several times trying to figure out if this is a problem just with my unit or if all Tivo Roamio’s have this same problem. Has anyone else noticed this?

    I get 5.1 sound with Netflix, if the movie has 5.1, some movies don't have that type of sound. When you start watching a Netflix program just push the TiVo info button and all the picture and sound info will show up in the top right of your screen.
    I am using HDMI to my HDTV than using the optical cable from the TV to my sound system, and my sound system shows 5.1 sound when it is there.
