Dolby 5.1

There are a lot of obnoxious people there. I’m a bit of a heretic, because I am less of a purist than a lot of those folks. One of the main reasons I adopted Tablo in the first place was so that I could use Roku as my sole source component for everything not on disc. I am heavily invested in UV and DMA titles (consumed via Vudu) and run Plex on a commercial grade NAS. My family also makes heavy use of Netflix, Hulu, Amazon and a few other streaming services. This setup means that my family gets a single simple interface anywhere in the house and I don’t have to play tech support much. I like the appliance-like stability of the Tablo platform, I’m just frustrated with how slowly the enhancements are coming.

How did you get that working? PCM stereo is the only thing being output to my amp from the Tablo App on Roku.

Dolby PLII works fine with my Tablo as well (via HDMI connected Roku to AVR). @luker does your AVR support PLII?

Just change it on your AVR! Should either be a button or a menu setting.

Yes and it displays on the fly what signal it is receiving. Which is PCM stereo for Tablo content, DD or DTS for my plex content, only Dolby PLII for Netflix since they updated that app to force DD+ which my amp can’t do.

You need to force it to Dolby PLII for the Tablo. That is how it works on mine, so at least you get center and surround information extraced from the 2.0 PCM signal.

Like @ John_Zanettos said, you need to manually select PLII for the Tablo stream - not allow the AVR to auto-select/switch.

Will test, kind of blows to have to manually select though. None of my other content needs to do this.

Hopefully AC3 pass through comes some day.

@luker can you a least try and let us know how it works out. It will be a stop gap until full 5.1 is added.

Yeah, will test tonight.

Thanks Buddy, please let us know how it works out. Also what AVR are you using?

That’s odd. Most AVRs will fall back to DPLII if the default for a given input is DD.

+1 the fall back to PLII automatically if no DD track detected - that is how my Denon AVR works (or conversely, the auto switch to DD+ / DD 5.1 from PLII when the appropriate audio is detected). No manual switching required.

This is the behaviour I expect out of my Yahama AVR, and what I’ve experienced in the past. Might be a setting is off in the AMP. I should move my Roku to my Arcam AVP700 in the basement and see what it detects.

I have a yamaha AVR and I have it set to DSP Standard that used DPLII to decode 2.0 on my Roku. When I switch to to Netflix it detecks the DD and DD+ but I keep it in DSP standard mode. I gather you are using Straight mode on your Yamaha that is why you are getting 2.0.

I use 5Ch Enhanced which auto detects the stream and displays the what is being sent to the amp.

My receiver basically remembers whatever the last setting it was on for two channel on a given input, which is usually handy. The only time I tinker with it is before or after listening to music (I hate faux surround applied to stereo music). This is nice, because I generally opt for something more sophisticated than DPL II.

Test was positive-ish. If I switch my amp to DSP Surround I get a popup that says Dolby Prologic II is being used. Sounds terrible though and very muted. If I switch back to 5 Ch Enhanced the sound is more natural and employs the centre channel, however the amp is doing all the processing and not applying Prologic II.

When I really want to hear quality audio on TV I switch to Live TV on my TV which passes the Dolby Digital stream to my AVR amp.

I can live with this until we get AC3 pass through, or I find another DVR solution :D. I kid, I kid.

Does your receiver offer other matrix surround options from THX or DTS? I have found that DPL II is a bit dated and not as good as some of the others. I don’t remember which one I am using at the moment, but it might be DTS Neo.

Yes it does, and when configured the way I like the amp automatically figures out from the audio stream which decoder to use, be it DTS or Dolby Digital or whatever.
