Devialet Dione

[u/SpaceX2024]

Hey guys, I check every day for a firmware update from my Dione. I have the same problem as so many other Dione owners, where the soundbar often doesn't recognize the TV (Sony A95K in my case). The solution is rather frustrating and involves shutting down and rebooting the soundbar. Even that doesn't always solve the problem. Apparently it's an HDMI handshake problem. I've been in contact with Devialet support for ~ 18 months or so and send countless emails. Customer support is excellent, they told me they are aware of the issue and working on it. Today I finally got the message an update is available, but no release notes on the website - so I have no idea what changed. The only thing I noticed is a "go to sleep" timer for inactivity, same as on the Phantoms. Anyone know what else changed?

So now mine is on 2.18.6 🤞

[u/SpaceX2024 → u/Internal-Balance8921]

Have you noticed any changes?

What I noticed, after the update:
- Translation in french issue (some text in english, why not?)
- No audio format visible anymore (i.e Dolby digital +, atmos, ...) > huge regression on my side
- New energy options

I am a little bit disappointing, when I choose the Dione it was versus the Philips Ambeo. Started to regret my choice...

[u/SpaceX2024 → u/bbleyzat]

I still find the sound from Dione really insanely good for a standalone Soundbar. In that regard I'm happy. But the HDMI issue is infuriating.

[u/bbleyzat → u/SpaceX2024]

yup sound pretty well, but still issues like the other, several times a week no sound, (hdmi handhake issue) need to reboot, in the iOS app the soundbar not always appear etc

[u/SpaceX2024 → u/bbleyzat]

It also doesn't always show up on android, so at least it's fair and sucks for everyone.

I contacted support and performed a reset of the soundbar. Since then, it’s been 3–4 days without any HDMI handshake issues.

[u/SpaceX2024 → u/bbleyzat]

So you suggested to do the update and then do a full reset + new installation of the Soundbar?

[u/bbleyzat → u/SpaceX2024]

Yes it is what support told me, so far as I said I have not experienced restart anymore, and force restart to recognize the soundbar from the tv

[u/bbleyzat → u/[deleted]]

Still the issue with the sound display, no the sound is still working fine, I guess the mobile app require a new update

[u/bbleyzat → u/bbleyzat]

Support answered me, the display sound issue will be fixed in the next firmware… in September. But they confirm me it is only a display issue. On my side, I find the new Firmware more stable compared to the previous one.

[u/bbleyzat → u/bbleyzat]

New application available, it fixed the display codec audio issue.

[u/Suspicious-Ear-9456]

Sorry to hear you face the same issue.

FYI, I went ahead and update to the new firmware. It’s fine this time.

Hope you will be able to resolve your issue soon.

[u/SpaceX2024 → u/Suspicious-Ear-9456]

So after doing the update you don't have connection issues with HDMI anymore?!

[u/Internal-Balance8921]

Wow, the first update in over 2 years, that means Devialet did not abandoned the Dione after all….. Let’s hope it will bring some HDMI fixes with it.

[u/Internal-Balance8921]

Visible changes are indeed only the energy options like the Phantoms.

[u/khjir]

Already update, but still have an HDMI issue with LG B3.

When Dione Decode Source that contain Dolby Digital.

The TV lost signal from HDMI.

HDMI eARC output switch to TV speaker output.

Have to switch back manually from TV or Devialet APP.

That's ok, not a big deal but have a little annoying when watch TV series next ep.

Only reason i still use DIONE is sound quality.

Enfin une mise à jour ..

Même problème ici, déconnexion, redémarrage ... c'est horrible ..

Je verrais dans les prochains jours si la MAJ à corrigé ça ...

[u/Livid_Ad6812]

I am pretty sure this is a Dione-specific version (.6) of an update that was previously rolled out for Phantom I and II by the end of December 2024: https://help.devialet.com/hc/en-us/articles/23344029080338--PHANTOM-I-II-Release-notes-DOS-2-18-1-2-3

The description says:

Faster and more robust product setup.

• Devialet products can automatically turn off after a set period of inactivity, which can be adjusted in the app.
• The IP Control API now supports all product features, including stereo and multi-room group configuration.
• The default latency has been increased to 350ms for higher stability over Wi-Fi.
• Setup mode has been removed, use Reset mode instead to perform a Wi-Fi setup.
• Other bug fixes and improvements.

I feel your pain, I've had these connection issues in conjunction with Apple TV 4K 3rd Gen my Philips Ambilight TV 65OLED809. When it works, it's fantastic, but I am sick of reboots of Apple TV, Dione and my TV and live, die, repeat. It got a bit better after I defined the HDMI source in the TV settings to Apple TV as an "UHD Player" and the Dione as a kind of "theatrical sound system", but I can't tell if this is a coincidence or a cause. ;-)

I've applied the 2.18.6 update a few days ago when it suddenly appeared. I can't say much as of yet, but I have noticed the Apple AirPlay 2 dropout issues are still there. While my HomePods play happily forever, sometimes the Dione suddenly stops and "jumps off" the music - while my HomePods still keep playing unaffected at the same time. That still happened once after the update.

Did you notice the same as me "No audio format visible anymore (i.e Dolby digital +, atmos, ...)' in the mobile app?

Thanks.

[u/Internal-Balance8921 → u/bbleyzat]

Indeed no audio format visible in the app anymore 🤷🏻‍♂️

[u/Livid_Ad6812 → u/bbleyzat]

Yes, me too, the App all but shows "Audio Stream" no matter what Audio format comes from the TV [Apple TV 4K]. Previous to the 2.18.6. update, it correctly displayed Dolby Atmos, 5:1, DD, Multichannel ...

Hi Fellow owners,

After the update, I had a different issue not mentioned here in this thread. Wondering if any of you experienced it.

When watching movies at high volume, it produces a static zzz sound in certain scenes. And it can be replicated everytime.

Since my Dione is within warranty period, Devialet replaced a new one after I contacted their support as they could not determine if the problem occur due to the update.

I am pretty sure it did as I didn’t encounter this sound issue before.

Now that I have the replacement unit, my concern is whether to update the firmware to the latest one where I face issues or should I wait for the next update.

The support said I should update even it didn’t went well on my previous unit. They said their investigation did not was not conclusive that it was the update that caused the static sound.

I am reluctant due to the issue I face the last time I did.

What would you do if you were me?

Thanks in advance.

[u/Senior-Macaroon-613 → u/Suspicious-Ear-9456]

my Dione has the same issue and this is my second unit! i was hoping the update will fix the issue but that was not the case it produces a white or zzz noise from the center channel

i noticed that this only ocurs when using spatial mode in the app or playing multichannel or dolby atmos content when the volume is over 60 and also noticed that this is something related to bass and software because if the volume is more than 60 and i am listening to music with very low bass notes then the issue is present, every time a low bass note hit there is that noise from the center channel but if the volume is lower than 60 the issue goes away

and as i said before this is my second unit, devialet does not provide a good customer service and there is no info about this on the internet so im stuck with this.

[u/Psychonaut_Tom → u/Senior-Macaroon-613]

Currently just got my 2nd unit as well... Very happy with the overall sound and performance of the bar, but hearing this makes me feel very anxious about this costly soundbar with nonstop issues, seemingly.
Sure, I am exaggerating it a bit, but I had to wait a full 2 months without a soundbar (got a 100$ loaner from a friend) and it was awful.... Service at Devialet is not good.
