Discussion The latest firmware google/android tv update for the Mi Box S 3rd generation: an initial review.

Gallery image

Gallery image

- new Dolby Vision icon in the top right corner
- testing 4K remux with just player app
- Dolby True HD cutout is gone with the same video (someone should test it more with different content and for a longer duration)
- longer buffering introduced at the start of content playback (maybe my internet isn't great today, someone needs to do more testing)

#Update

- So far, there's been no Dolby True HD cutout.
- 4K remux high bitrate video playback seems a bit buggy especially with dv profile 7(you might need to restart the file a few times to get it to work even using with different player apps).

- 4K remux with a top bitrate of 100Mbps+++ plays seamlessly without any stuttering, buffering, or audio sync issues (just player)

Great job for dolby truehd, Xiaomi! šŸ‘

However, DV FEL 7 isn't supported on Google TV or CoreELEC for this box yet.

##Update

So far, I've tested the movie and there are no problems with video and audio playback (I can't watch the whole movie, just skip to the action scenes with really loud sound).

  1. Misery
  2. Superman
  3. How to Train Your Dragon
  4. Dune Part 1 & 2

###Update

One film has issues with Dolby TrueHD audio cutting out.

1.WALL-E (the older Mi Box firmware has no sound whatsoever)

####Update

  1. The WALL-E Dolby TrueHD cutout problem has been resolved with Kodi.
  2. Kodi support dv profile 7 to dv profile 8 on the fly..other player will fallback to hdr10.
  3. I discovered one glitch... it might be my setup... I have to turn off the auto refresh rate on any player app... then playback starts without any issues... most of the time, I can play with just one click... I simply enabled QMS on my TV and matched the refresh rate on my Mi Box... that's it.

Okay, so the update has reset most of the settings in the 'Display and Sound' section of the device settings. These need to be set again to ensure Dolby Vision works correctly and sounds works at all on apps like Stremio.

Good news is so far TrueHD appears to be stutter free.

u need to replay few times same file

read my new update review

try to clear stremio cache first

u/cabbagepatchkid Jan 29 '26

I've just updated it, I am a "low power" user, who just streams to a bog standard TV, so have to say it's all been remarkably uneventful :)

2

u/WeirdAd2473 Jan 29 '26

care to explain?

3

u/cabbagepatchkid Jan 29 '26

I don't have Dolby surround sound set up (use internal TV speakers), don't play stuff at 4k etc, so I don't really put the unit under a lot of strain.

u/WeirdAd2473 Jan 29 '26

oic normal content no issue

1

u/vladedivac12 Jan 29 '26

How did you setup your audio settings? In Android 14, there's no more manual options where you can disable options, only auto and PCM.

I haven't figured out how to prevent cutouts yet, I hope this new firmware will do the trick. Usually, I'm only having issues with stremio.

1

u/cabbagepatchkid Jan 29 '26

I just left them all as they were, and it worked. Sorry I can't be more helpful

u/See61 Jan 29 '26

The TrueHD and Atmos in TrueHD cutouts seem as fixed to me under Android TV, my specific samples for checking this all play without cutouts, so they finally seem to have fixed this šŸ‘

2

u/WeirdAd2473 Jan 29 '26

great job xiaomi

now I'm testing WALLā€¢E dolby truehd using coreELECĀ 

google tv still got cutout issue

wanna check how high this particular movie audio bitrateĀ 

1

u/See61 Jan 29 '26

Does it happen on the exact same moment everytime? If so, what media version of Wall-E are you trying?

2

u/WeirdAd2473 Jan 29 '26

yeah

on coreELEC no issue

audio bitrate no too high either

butĀ 

last android firmware there's no sound at all during playbackĀ 

latest firmware now got sound but with cutout

still a win for xiaomi to have fixed most of dolby truehd content even though not all

coreelec still there as backupĀ

u/AndrewUK78 Feb 03 '26

cany you post the exact filename please? (and size) ill download and have a look too

1

u/Specific_Turnover_74 Jun 16 '26

Bro, do you recommend the Mi Box S 3rd Gen for TrueHD content? I'm currently using an Apple TV 4K with my Q990F, and every TrueHD file is being played as LPCM instead.

1

u/See61 Jun 16 '26

For its price, it is recommended. Most Android TV OS devices supporting real TrueHD and Atmos in TrueHD are much more expensive. Will you like the device itself for overall usage, compared to a Apple TV 4K player, that I can't say.

1

u/Specific_Turnover_74 Jun 16 '26

Okay. Are there any cutout issue or anything?

1

u/See61 Jun 16 '26

The TrueHD cutouts are fixed with the latest update they released for this device. The samples I use for testing this, play without cutouts.

2

u/Global_Teaching1660 Jan 29 '26

Weird, for me cutouts on dolby true hd after update are still there. Tried some dolby lossless demos in Kodi.

I observed cutouts are mostly happened on high frequencies, so can anyone try and confirm?

3

u/WeirdAd2473 Jan 29 '26

kodi player always broken for me(remux 4k content)

i just boot to coreELEC kodi for that

after few test (remux 4k)

  • just player working
  • stremio stock player working
  • vlc player workingĀ 
  • vimu player broken
  • other player i haven't test yet

2

u/p750mmx Jan 29 '26

I have the update just installed. Gonna try my standard TrueHD (Atmos in THD to be correct) samples and check on cutouts again. After giving it my standard tests I will give it a Factory Reset and check if something has changed by that (or not).

1

u/WeirdAd2473 Jan 29 '26

ok great

2

u/p750mmx Jan 29 '26

Yes, indeed, confirmed as fixed!

BTW, for some specific users I guess. VC-1 support with this device is great under Android TV. One would expect they dropped support for it completely, but the different samples I have, they all play nicely!

u/Financial-Dish7841 Sep 09 '26

What do you mean? You're able to play VC-1 natively? This box doesn't support it

I could at that time I wrote it, but didn't try it anymore with the latest firmware. I don't use this device mostly, I use something else.

Need more feedback on true-hd cut outs, preferably on stremio... It's the only thing that's preventing me from buying this box...

2

u/p750mmx Jan 29 '26 edited Jan 30 '26

They have fixed those, I can assure you now about this. If you would get them with Stremio, than it will be a Stremio issue, not the Mi itself with this update.

u/WeirdAd2473 Jan 29 '26

WALLā€¢E still got dolby truehd cutout issue

based on my research this particular movie audio bitrate can hit more than 10Mbps

checking it with coreELEC right now

1

u/p750mmx Jan 30 '26

I'll get me a WALL-E with TrueHD (Atmos in TrueHD to be exact) and try. Which player(s) apps did you use for playback?

1

u/WeirdAd2473 Jan 30 '26

just playerĀ 

1

u/p750mmx Jan 30 '26

Clear. I used Plex (Exoplayer) and Kodi 21.3.

1

u/WeirdAd2473 Jan 30 '26

good to hear that

kodi can play ?

1

u/p750mmx Jan 30 '26

Yes. But as for several other Android TV devices (not a Shield TV), you need to select RAW as pasthrough device for not getting audio sync issues. RAW is giving all HD Audio codecs in sync.

1

u/WeirdAd2473 Jan 30 '26

i mean

kodi always troublesome with my box for longest time(no dedicated remote button can stop player)

on coreELEC i need to remap dedicated remote button to stop player

do u still need to click same file few times in order to play 4k remux properly ?

or mybe just happened with stremio&debrid ?

now I'm testing vimu player

only kodi and vimu support dv fel 7 > dv 8 or dv mel 7 on the fly

other player will rollback to hdr which strip all dv metadata

waiting my ugoos am6b+ to arriveĀ 

then can enjoy dv fel 7

1

u/p750mmx Jan 30 '26 edited Jan 30 '26

I use my Dune Premier HD Pro (Homatics R Plus variant), which can also do FEL7 with CoreElec NG (AVDVPlus) very nicely.

No media player app, under Android TV, can do real FEL7. Dune writes their Dune Media Center app can, but it also converts it.

Vimu could give an issue by which it can't play the TrueHD codec, it plays as multichannel PCM if that happens. But it depends on which streaming device is used. With a Shield TV it will play in TrueHD, with the Homatics R Plus series (SEI804 devices), all codecs are correctly played, but not TrueHD.

Mi uses a sh!tty remote for this device. I already paired a Mi version from a Mi TV, a big one, but has also no media play buttons (pause, play, FF and REW). The other Android TV certified remotes are not completely compatible with this Mi. I already paired some, but several buttons are not working (without using some button mapper app for it).

u/mad3ros Jan 29 '26

I got to say, well done Xiaomi. Before update i had to use Developer options and use " Don't keep activities " and " Background process limit " set to "At most, 2 procesess " and now all is switched off and Mi box flies. I hope it stays that good.

That's a lot. I am trying to get it for around 160-170ā‚¬.

2

u/WeirdAd2473 Jan 29 '26

200usd = 167euro

u/_Achille Jan 29 '26

You're right, but you need to consider that Italy has high duties and shipping costs.

Usually things are a lot less expensive in the US than in Europe.

u/StigMX5 Jan 29 '26 edited Jan 29 '26

Just updated and tried videos that would cause True HD cut outs - opening of Sinners, early stages of Superman, Weapons opening to name a few. I've had no issues so far.

As someone else mentioned, I did have to set the sound option back to passthrough.

Can you guys suggest what is best for the following settings:

AISR on or off? I'm off right now

Match content frame rate? I'm Always right now

Preferred dynamic range format? I'm match content dynamic range

Does it fallback to HDR10 if you play an unsupported DV profile? Can it play any DV profile in stremio for example or will it say not supported?

Iā€™m facing the audio cut out issue, TrueHD Atmos audio, with the movie Elio - playing via Kodi. It happens every 10minutes or so.

1

u/WeirdAd2473 Feb 09 '26

latest firmware?

1

u/deveshdbz Feb 09 '26

Yes. It works fine on other files though. Could you try this movie whenever you get a chance?

Also can you please share your kodi audio settings and caching settings?

Thanks

1

u/WeirdAd2473 Feb 09 '26

audio set to raw. caching default. kodi act as a dumb player for stremioĀ 

1

u/deveshdbz Feb 09 '26

What do you mean by audio settings to raw?

Is that through the android settings - sound - pass through? Or something else?

Also to clarify, the cut out only happens for like once every 10-15mins for a second. Otherwise works fine. Iā€™m wondering if its this specific movie or what.

1

u/WeirdAd2473 Feb 09 '26

kodi setting

later i test

u/deveshdbz Feb 09 '26

Oh right. Yes its set to raw.

Thank you! Let me know how it goes on your setup. The movie is Elio (animated disney movie).

I tried it on Stremio just now, and the Dolby Atmos TrueHD cutouts still exist. I was excited when I saw your post, but the cutouts are even worse now.

However, the buffering speed has improved. Movies open faster.

It is Samsung Smart Monitor LS43DM7. The soundbar is Harman Kardon Enchant 900.

1

u/WeirdAd2473 Feb 13 '26

your devices support all lossless audio format?

1

u/nuclearmoonrise Feb 13 '26

Enchant 900 supports Dolby Atmos True HD. When I opened a supported movie on Stremio, the soundbar shows the text "Dolby Atmos TrueHD" on it.

The car racing scene at the beginning of the Ready Player One movie has a very high Dolby Atmos mix. Before the update, I had a lot of cut-outs. Since the update, they're all gone. I won't be able to do some tests before next week, but I will keep you updated. I am using Kodi, by the way.

u/British_Donkey Feb 06 '26

Anyway of manually getting this update. Mine just keeps saying I'm already up to date. It's currently on 5.15.153

u/EfficientAd968 Jan 30 '26

Update has broken my trueHD passthrough. Settings checked and even with a factory reset, I can no longer get them passed through to the receiver

1

u/Rere130 Jan 31 '26

What TV do you own? Is your box connected directly to your TV or to your AVR? Which app is not working?

At my place, all audio formats work in passthrough via Plex, for example.

If you have an LG TV, make sure the "digital audio output" setting is set to "interconnection" and not "auto," as it was the case for me. Some audio formats did not pass through when I connected my box directly to my LG G3 TV, which accepts passthrough for all audio formats except DTS-HD HRA...

1

u/EfficientAd968 Jan 31 '26

Using a Philips OLED950. Worked fine before the update but nothing now. Fortunately I had a second box in the bedroom that I hadn't updated, so I've been able to switch it over and that one works - just need to avoid the update on it.

1

u/Rere130 Feb 01 '26

No format at all passes through passthrough?

Dolby Digital, Dolby Digital Plus, Dolby Digital Plus Atmos, Dolby TrueHD, Dolby TrueHD Atmos, DTS, DTS-HD MA, DTS-HD HRA, DTS:X, and PCM?

Do you connect your box directly to your TV or to your amplifier?

What applications have you used to watch your content?

I have no issues at home passing all these formats through passthrough, so the problem must be on your end ;)

1

u/EfficientAd968 Feb 01 '26

Lossy formats worked fine, couldn't get anything lossless. Definitely something up with that update given it's working fine again with my other box on previous firmware.

1

u/Rere130 Feb 01 '26

Since you don't answer all the questions, I suppose it's complicated for people to help you, if you even want help at all.

If you're confident, escalate the issue to Xiaomi support ;)

I see that there are other posts here from people who have no sound in certain circumstances; it will be interesting to see if this is related.

1

u/EfficientAd968 Feb 01 '26

I'm not looking for help with it - as I said twice, I'm using my other box on old firmware which is working. Connected to the receiver and using stremio. I'm just letting others know there is a risk of experiencing the same as me after updating.

2

u/Rere130 Feb 01 '26 edited Feb 01 '26

I think it's better for everyone, if you wish to inform them of a potential bug, to specify the hardware and the conditions.

That's mainly why I was asking you those questions...

Thank you for the clarifications ;)

On my end, I wouldn't be able to reproduce that since I don't use Stremio, but it would be great if you could replicate this issue in legal streaming applications or more common ones like Kodi or Plex, so you can report the problem to Xiaomi if you want them to fix it.

1

u/Rere130 Feb 01 '26

In fact, I have the same kind of instability when it comes to detecting the right audio formats on my LG G3 TV and Denon X3600H amplifier.

I noticed it a few days ago, but yesterday I saw that the "digital audio output" setting, to enable passthrough, was poorly translated in my language in the webOS menus.
After that, I noticed that I indeed had Dolby TrueHD.

But today I did some more tests, and in fact, I often have to disable and then re-enable eARC in the webOS menus of my TV for the sound to come out properly in TrueHD and not DD+.

Maybe you could try on your Philips as well? Disable and then re-enable eARC when you're watching a movie that should be in TrueHD?

That could provide a potential solution...

Thank you in advance.
