It would help to know more about your configuration. Is the Tivo connected to the Denon, then Denon to TV. Or is the Tivo connected to your TV then ARC to Denon.

I will assume that your Tivo is connected to the Denon first. If so, then the no audio when setting Tivo to output PCM is the first thing to figure out. You should be able to set the Tivo for Dolby out or PCM out and your receiver should play sound with either Tivo setting. Which tells me you have a setting issue on the Denon. The Denon readout should show Dolby or Stereo depending on which setting you use on the Tivo. I am not familar with the Denon settings, but solve that issue first and then we can address the clicking if it is still there.

 

That clicking sound in the AVR is usually the result of a relay activating to switch amp assignments (e.g., selecting between SB/FH/FW in a speaker setup greater than 7.1) and is entirely normal, but in your case it would appear to have a different cause.

As mentioned by the poster above, it would help to know more about your AVR setup (and BTW I agree that in any case you should be getting output whether Dolby Digital or PCM). What is your speaker layout? What surround parameter mode are you using? What are your amp assign and speaker config settings? Are you using a Quick Select for the TiVo input (QS will memorize the surround mode for a given input and signal type and therefore minimize amp switching)? How is the TiVo connected to the AVR? If by HDMI, are you using a known good cable (HDMI 1.4 or better)?

I am not familiar with the audio settings in the Edge and do not know whether there are any differences over Bolt or Roamio models. In my Roamio the only options are either Dolby Digital or PCM. Note, however, that if you enable the Screen Reader, then Dolby Digital is not available.

 

Thanks so much, guys! I figured it out. Your references above helped me dig deeper into the Denon setup on the receiver itself and with the Denon app. Tivo is connected to Denon via HDMI only, then Denon to TV. I have a 5.1 speaker layout. When I looked at the Surround Mode in Denon app, it showed 'Stereo'. I tapped on 'Dolby Digital' and now I get sound out of my speakers using either option of Dolby Digital or PCM on the Edge (so that fixed the PCM audio issue). Apparently just doing that single change also fixed my clicking issue on the receiver when I change channels on the Edge. So now I can change channels AND keep the Dolby Digital option set on the Edge (which is ultimately what I wanted). I guess the 'Stereo' setting was causing the clicking to happen on Denon as I changed channels (it would go from Dolby Digital to Stereo to Dolby Digital with each channel change). So glad to get this resolved. I powered down they system and then backup to make sure everything stuck, and it did (no issues). So I think I'm good now. Again - a million thanks!

 

Good to hear.

Don't forget: Quick Select is your friend! And it is generally a good idea to save your settings to a USB thumbdrive for safekeeping in case you need to restore them at a later date.
