X60 issues

[astateofmind]

1. It needs a volume control for the rear speakers set. Not independently like left-right channels but as a set. As it is now if the rear speakers are a bit further away I can't hear them at all.

If possible make it controllable in a future firmware update, at least through the application.

The team already acknowledged this issue in a comment on a different thread and I hope it's fixable through an OTA. I'm just adding here for more visibility.

2. Dolby Surround 5.1 tests fail.

With my old vizio when playing dolby tests videos on youtube on my LG TV the surround (rear) speakers are working ok, when the test is playing the sound for the rear left (surround left) I hear it on the rear left.
With the X60 it comes from the soundbar/front. Tried with upmixing on and off.
Why?

Shouldn't it still be on the rear speaker? Are the channels mixed in a wrong way?

The center channel was playing at the right test in both cases. So it looks like there is some problems in routing a 5.1 signal - the rear sound should be ... in the rear.

Is there no proper support for Dolby 5.1?

This video worked ok on my vizio, not on the X60 :

I tried a 7.1.4 test and seemed to be ok, the sound was playing on the right channels.

This video worked ok on the X60.

I'm on V8 firmware.

Can someone test these video on a their setup and report back if they hear the channels properly? Maybe my set is broken or something.

I will keep adding issues if I find more during tests but so far these 2 are the most important.

Build quality and sound quality seem ok otherwise.

I totally agree with both of your points, and here’s a practical, straightforward fix in one go. It makes complete sense for the soundbar to let you adjust the rear block (R+L) as a whole to compensate for distance. I’d ask the team to enable this via OTA/app as a “Surround Level (Rear Block)” control and, if possible, add distance/delay per block plus a test tone. Meanwhile, move/angle the rears closer (about 110–120° from the listening position and slightly above ear level, or use tripods), and avoid tweaking L/R separately because it often throws off the balance. If your room is very absorbent, raise the overall volume a notch and lower front/center a touch (if your model allows) so the rears “breathe.”

About the 5.1 YouTube test coming from the front: that’s almost always a signal-chain thing. Many TV apps output PCM 2.0, and the bar upmixes it—hence “rear left” coming from the front. The fact your 7.1.4 test maps correctly suggests the X60’s decoding is fine and the issue is the source/settings.

Set your LG TV to Passthrough/Auto (not PCM), enable eARC if available, turn off AI Sound/virtual effects during testing, and enable Deep Color/Enhanced HDMI on the port you use. On the soundbar, keep Upmix OFF for channel tests and, if possible, confirm the input reads Dolby Digital 5.1 / DD+ 5.1 (not PCM 2.0). Then compare YouTube with a known-good 5.1 source (Netflix/Disney+/Prime or a DD/DD+ 5.1 file via Fire TV/Shield/Chromecast/Apple TV 4K). If the rears are correct there, YouTube/app is the limit—not the bar.

If it’s still wrong, try changing the path (Source → TV → eARC → X60 vs Source → X60 (HDMI IN) → TV), swap in an Ultra High Speed HDMI cable, reset audio settings on TV and bar and reconfigure only the essentials, and check for a newer firmware (you’re on V8). If it persists, share TV model, connection path, detected format (DD/DD+/PCM), the test link with timestamp, and your result with a known-good 5.1 source so it can be escalated.

Build and sound quality on the X60 are solid—adding that rear-block level via OTA would round it out nicely for larger rooms.

 

[Ultimea Team]

Thank you very much for your time and effort in conducting such thorough and professional testing of the Skywave X60 and providing such clear feedback.

To help us resolve this issue, please provide the following information:

Device Information: The X60's full serial number and current firmware version (you mentioned V8, which is excellent).

Playback Link: Please clearly indicate the specific device connection you used during testing (e.g., LG TV - HDMI ARC/eARC port - X60).

Key Test Video Link: Please provide the link to the Dolby 5.1 test video that you mentioned as not working correctly. Our team will need it to replicate the issue.

Once we receive this information, we will immediately submit it to our R&D team for in-depth analysis and seek a solution or provide a clear explanation.

Sincerely,
The Ultimea Team

Thanks for your reply.

1. "lower front/center a touch (if your model allows) so the rears “breathe.”

It doesn't

It's very weird that this features which I would consider basic are missing ...

And worse, I think that because of the expected distance to the rear speakers to be minimal their default volume is lower than the front soundbar, quite a bit.

Do you think this could be solved with an OTA upgrade?


2. "Set your LG TV to Passthrough/Auto (not PCM), enable eARC if available, turn off AI Sound/virtual effects during testing, and enable Deep Color/Enhanced HDMI on the port you use. On the soundbar, keep Upmix OFF for channel tests and, if possible, confirm the input reads Dolby Digital 5.1 / DD+ 5.1 (not PCM 2.0). Then compare YouTube with a known-good 5.1 source (Netflix/Disney+/Prime or a DD/DD+ 5.1 file via Fire TV/Shield/Chromecast/Apple TV 4K). If the rears are correct there, YouTube/app is the limit—not the bar."

As I already said: it works correctly with my old vizio 5.1 system with the same source - same video on youtube playing on my TV, exactly the same settings on the TV, just unpluging the cable from the vizio and plugging it in the X60.

X60 reports "Dolby Surround" EARC when playing that video on the TV ... there is no granularity on what the soundbar reports

V8 seems to be the latest firmware.

"If it persists, share TV model, connection path, detected format (DD/DD+/PCM), the test link with timestamp, and your result with a known-good 5.1 source so it can be escalated."

LG OLED C1

Youtube app on the TV - output EARC on the Soundbar. Detected format: Dolby Surround (no other information on the soundbar or in the app).

The old vizio was telling me exactly the format and how it was encoded (EG: Atmos - Dolby Digital). X60 doesn't report this information
Again, a weird decision ...

Tested with this video on both my Vizio M51ax-J6 and on the X60. On the Vizio it was playing correct, on X60 it was NOT playing correct.

Also did some more testing with My computer connected to the TV and then EARC to the soundbar, PASSTHROUGH, DEEP Color enabled, and using the files from here and comparing my old vizio soundbar with the X60

Files location: https://drive.google.com/drive/folders/1JxmeedtAtgmoafXv9rroiDOS2vEX7N4b

Files used:
AAC 5.1
Dolby Atmos E-AC-3 5.1.2
Dolby Digital AC-3 5.1

And
Dolby Atmos TrueHD, E-AC-3 5.1.4
Dolby Atmos TrueHD, E-AC-3 7.1.4

Results:

Vizio - All files working correctly

AAC 5.1 - reported DOLBY AUDIO, DOLBY MAT
Dolby Atmos E-AC-3 5.1.2 - reported DOLBY AUDIO, DOLBY MAT
Dolby Digital AC-3 5.1 - reported DOLBY AUDIO, DOLBY MAT
Dolby Atmos TrueHD, E-AC-3 5.1.4 - reported DOLBY AUDIO, DOLBY MAT

X60 - all reporting DOLBY SURROUND and no information about the encoding.
AAC 5.1 - Working (the only one that's working).
Dolby Atmos E-AC-3 5.1.2 - NOT WORKING - rear channels in the front
Dolby Digital AC-3 5.1 - NOT WORKING - rear channels in the front
Dolby Atmos TrueHD, E-AC-3 5.1.4 - NOT WORKING - rear channels in the front

But the best examples are these 2 files:

"Dolby Atmos TrueHD, E-AC-3 5.1.4.mkv" and "Dolby Atmos TrueHD, E-AC-3 7.1.4.mkv"

On the 5.1.4 video the rear speakers are playing in the front BUT the rear height speakers are playing correctly in the rear.

On the 7.1.4 video EVERY channel is playing in the correct position.

Testing with the TV included mediaplayer (could only play 2 files):

Vizio: worked ok with both files.
X60:
AAC 5.1 NOT working (hmmmm)
Dolby Digital AC-3 5.1 - working ok.

I was trying to test with my AppleTV but that seems to make a mess of the DolbyDigital and outputs everything LPCM, apparently stereo?

Something is really wrong when playing 5.1. It's like the system considers 5.1 a 7.1 with missing channels and uses rear channels as the surround channels and it leaves it with no rear channels, it that makes sense. Seems like it treats the 5.1 like a 7.1 with empty rear channels - sometimes at least.

If this is the case this should be solved ASAP as well. And the rear volume

I wonder if these problems can be solved by an OTA upgrade or needs some rewiring

Btw, I didn't test with V7. Is there a way to install V7 again?

 

[astateofmind]

Also was testing with this video:

And sometimes it works ok (I can hear all speakers) sometimes it doesn't. Sometimes I have to unplug the HDMI from the soundbar and plug it back.

Maybe it just a problem of handshake between devices?

 

[astateofmind]

What's annoying is that everything works ok with my old vizio and I don't have this kind of problems ...

 

[Ultimea Team]

We have submitted your test results and issues to our product team. They are currently investigating the cause and developing a solution.

Thank you again for your professional feedback and patience. We will continue to update you on progress via private messages.

 

[astateofmind]

Tested again with the "Dolby Atmos TrueHD, E-AC-3 5.1.4.mkv" and "Dolby Atmos TrueHD, E-AC-3 7.1.4.mkv" files this time playing them with this setup:

AppleTV (Infuse player) - LG C1 TV - X60 (EARC). Soundbar reports Dolby Surround (It might be LPCM - the soundbar doesn't report the encoding).

Exact same results:

With the 5.1 file the rear channels are playing in the front (wrong), the rear high channels are played in the back (correct).
With the 7.1 file every channel plays in the correct location.

So I guess that when the system tries to play 5.1 it will send the rear channels to the surround (in the soundbar) channels?

BTW: serial number: looks like there is no serial number on the device?

Salut, je rentre dans le fil de l'histoire. Il faut peut-être essayer de l'Atmos via Amazon music, Apple music, kobuz ect.....?
Sinon autres solutions, à l'attention de la Team Ultimea, je suis disponible pour tester le Skywave X60

 kito

My x40 does similar, struggles to play all dolby atmos content from Netflix within Sky Glass TV. It's like Netflix doesn't support or recognise Ultimea soundbars, mine will only play in Dolby Surround.
I can get Dolby Atmos through direct sky programs though and Amazon

Hi there

I also have the Skywave X40 and in my case Netflix outputs Atmos without issues, so it’s probably not a defect with the soundbar.

Keep in mind two key things about Netflix:

1. Plan: Atmos is only available on the Premium plan.
2. Audio track: even if the title supports Atmos, it usually only shows up on the “Original version (VO)” of the content. In other words, in the audio selector you need something like “English [Original] • Dolby Atmos” (or the title’s original language). Many dubbed tracks are limited to 5.1 or Dolby Surround.

Also, check these settings on your Sky Glass/TV:

• Audio output set to Bitstream/Passthrough or Auto (not PCM).
• eARC/ARC enabled and CEC turned on.
• While testing, disable modes that alter the signal (e.g., Virtual Surround, Night mode, Voice enhancement), as they can block a clean Atmos bitstream.
• Sign out/in of the Netflix app or update it in case it’s a Sky Glass app glitch.

Since you’re getting Atmos with Sky and Amazon, the X40 is fine; the bottleneck is usually the Netflix app, the selected audio track, or TV configuration.

Quick checklist

• Netflix plan: Premium.
• Audio selector: “Original version (Atmos)”.
• TV settings: Passthrough/Auto, eARC ON, no extra audio processing.
• Make sure the title shows the “Dolby Atmos” badge on Netflix.

If it still doesn’t appear, as a temporary workaround try Netflix from an external streamer (e.g., Fire TV/Apple TV) into the TV, with the TV sending audio to the X40 via eARC.

Good luck! If you want, share your exact TV model and we can walk through the steps together.

Well the Skywave X60 is 7.1.4 and the Neuracore triple-core DSP is likely the cause of the sounds coming from different drivers... I'm no Ultimea or Dolby Labs engineer or anything but it probably is trying to maybe upscale to the 5.1 signal to match the driver count in the X60. The Specs list the Skywave X60 having a total of 12 speaker drivers.

You just got a be absolutely sure your source and settings are correct. CEC via EARC when properly setup basically gives your connected devices full control over your TV. Hard to tell what your Vizio 5.1 is sending over CEC and settings are automatically adjusted... Have you considered factory resetting the LGC1?

I'm sure that if it's a software or processing thing Ultimea will take care of it in the next firmware!

This may sound goofy as a last resort but have you tried a new HDMI cable?

Good luck.

Yes that's what I have to do I have to stream Netflix from my xbox into my sky glass then to the soundbar for atmos. It's just annoying.

If these issues cannot be solved I might have to downgrade to X50.

Can the x50 independently control the rear speakers? I see that it has a “Surround” button so I would expect that controls the volume of the rear speakers and ONLY the rear speakers?

We've consolidated all of your concerns (including Atmos identification, 5.1 channel mapping, and rear volume control) into a single, top-priority case, which is being handled by our product team.

We'll continue to update you on the progress of our internal testing and strive to find a solution for you as quickly as possible.

HDR also does not work when using the HDMI pass through on my Xbox series. X.
Only works when I switch to another HDMI port. But when you switch to another HDMI port, you lose Dolby Atmos. It says Dolby Atmos on the soundbar, but it doesn't work. You have to switch to Dolby digital to have HDR and surround.

This really needs to be fixed.

And, like the main post. Something is funky when playing the Dolby Atmos test on Xbox while using pass-through. The right side surround sounds fine. But the left side sounds like it's not working at all . Also when it goes to the rear speakers the test on the right rear, Both rear speakers are firing at the same time, this also happens with the left.

And sorry I need to add one more. When switching from my Xbox to YouTube app , Or any other app on my TLC TV. The volume is incredibly loud for a few seconds.

I have this also on my x40 I have reported this also.
I also get the loud output when turning the soundbar on I have to quickly turn volume down to zero whiles it's coming on if not the whole house and neighbours get woken up.
Really need a firmware update ASAP

Hi,

We deeply understand the frustration you and your neighbors are experiencing. This sudden, loud noise is truly unacceptable.

The popping noise issue you described with the X40 is consistent with some feedback we've received on other models. This is often related to the initialization process when the device wakes up from standby.

We recommend trying the following steps:

Reset the device to factory settings to return it to its default state.

In Settings on the official app, find the "IR Passthrough" option and make sure it's turned off.

Also, set the system beep volume to the lowest setting.

Your patience and detailed feedback are crucial to us. We hope the above steps will immediately improve your experience, and we sincerely appreciate your understanding while we address the underlying issue.

Happy exploration!
