NEW - Tablo Firmware Release 2.2.22

Happy Thursday Tablo fans!

A new firmware update is on the way for your Tablo… and it’s got a big fat feature that you guys have been asking for:

5.1 SURROUND SOUND!!! (Read more about this new feature on the Tablo blog and on the Knowledge Base.)

Like previous releases, this firmware will be offered in a staged rollout. A small portion of users will have access to this firmware immediately. We will increase access slowly as we judge feedback and distribute the firmware to increasingly larger batches of units over the coming week or so.

Here’s what you can expect…

Release Notes for Tablo Firmware 2.2.22

• Support for 5.1 Surround Sound passthrough
• Workaround for Fire TV 4K/Fire TV Cube video stuttering issue
• Improves reliability of new firmware update downloads on poor network connections
• Other reliability and performance enhancements

NOTE: Post-upgrade database processes (if needed) may take several minutes to complete. During this time the LED will be blinking. Do not power down the Tablo until the LED is solid again.

If you own an Amazon Fire TV 4K dongle or the new Amazon Fire TV Cube, you’ll also be happy to hear that Tablo firmware 2.2.22 includes a workaround that solves the video stuttering behavior caused by a video decoding issue in the Fire TV firmware. Enjoy!

I’ll be the first to man up and admit, I was wrong. I was 100% positive that you guys wouldn’t get 5.1 on current hardware.

Thank you.


WOW !!!

That’s Great !


No Beta Testing Needed ?


Oh we beta tested!

Our beta team is just pretty awesome about keeping big secrets under their hats!

(Thanks guys!)


It’s been tough seeing a few threads over the last month complaining directly about no surround sound and no FireTv support, when both were in the beta being tested. So it is great that it is now out in the open.

I will say that the biggest weakness is no PC support for surround sound. I do use my PC a lot for the Tablo, so I will likely keep most of my recordings in just stereo. But I have a 2nd Tablo now, and I will use that Titans games and other big events.

Another tip for Android phone users. If your phone is Dolby compatible (like mine, a Moto G6), you can get surround sound audio to play on it by using the link in Chrome. Then go to settings and select “external player” for sound. Install VLC on your phone and select that as your player. (The standard Android app won’t play audio if surround sound is enabled).



I was liking the the VLC for my phone to play downloaded recordings (from OTA2go app) until I found it didn’t support subtitles.

Aware of any player that does ? (on the Android platform)


Good question. I honestly don’t know enough about the players out there to give an answer.

Hi – Just clarifying, does Ota2Go play the subtitles on those videos if you use the internal player? Ota2Go only includes subtitles in the “TimeSaver” (i.e. direct copy) method, rather than the “SpaceSaver” (i.e. transcode) method. Perhaps that’s at the root?


I wonder how much the size of the output file will change with 5.1. It is going to be bigger for sure.


Hi Steve

Not to hijack this thread… but the internal player does show captions.

My problem is I want to cast the downloaded mp4s to a larger TV and the Android VLC won’t support captions.

The engineering team says it shouldn’t be significantly larger.

What??? 5.1 !!! I never thought I’d see the day. Can’t wait to try it out!


On Galaxy S7 go to settings, sound, advanced and you’ll see DOLBY! WORKS GREAT!!!

I wonder what will become of the tablo forum?

With Dolby 5.1 and the Cube fix will users have run out of topics to post about?

Of course if you are old enough and have been to a number of rock concerts, Dolby 5.1 is kind of like listening to sound in a very bad and weird echo chamber.


I was wrong too.
I was one of the first user to buy a Tablo and after all this time I really tought this was really BS.
I really tought that the hardware was the limiting factor

ATSC 3.0, 802.11AC on ATSC 3.0 Tablo.

Don’t crash on weak signal. LOL

I have multiple tablos and mine don’t crash on a weak signal.

So are we talking about signal strength or sound to noise ratio?

Mine don’t either, actually.
I removed the channels triggering the problem.
Life goes on.

Hi Tablo,
Thank you for 5.1!
Questions…Do we lose a tuner in the process of using 5.1?
From what I gather, The standard Fire TV app using the Fire TV2, will not be able to play 5.1, unless we use the FireTV preview app. Will ther be an update to the regular Fire TV app?
Thanks again for the feature…
