HDMI-CEC (SIMPLINK) "Auto Power Sync" works only during configuration


Recommended Posts

Dear All,

I'm new here hoping to find a solution to my problem, after now trying around for almost two days without any result.

My set-up:
- LG OLED55C97LA OLED TV
- Nubert nuPro X-3000 (Pair of active speakers)

The active speakers are connected to the TV via HDMI-ARC on both sides. I'm aware that my configuration might be a bit unique, however I have the feeling that it is the TV / webOS which is messing arround with me.

After connecting my speakers to the HDMI-ARC, changing the TVs output to the HDMI 2 (ARC) is started the device configuration. I was glad, as typing in "Nubert" into the device selection of both "Home cinema system" or "Bluetooth / Soundbar", the webOS brought up a configuration to select.

During the "try-out" phase of the configuration process, turn on and off the power of the speakers works perfectly - even very fast! After configuration, sound comes through the speakers very well and I can adjust the volume. However, when I turn of the TV the speakers will remain on. Same vice versa when trying to turn everything on by only starting the TV.

Does anyone face a similar problem and might have a workaround for this? It is very frustrating and annoying, as it works perfectly in the configuration - but not later on.

Thanks for your help!

Sebastian

@JetForce  You might want to check via the smartphone app, that the auto on/off setting is set to active, so it has some "Staying power" as the TV might not be able to control this setting. Also read the notes:

 

(seen under the ADVANCED section)
– auto power
The nuPro’s electronics have an automatic standby function that automatically
switches the loudspeaker into power-saving mode when
it is not needed - and also switches it back on again automatically. If
the menu item off is selected here, this is automatically deactivated.
Note: For more information on the stand-by automatic function, see
page 6 in the Design and Engineering section (you need to email the company to get this I think).

However, as the HDMI/ARC adaptor goes into the USB socket on the speaker, see this section:
"Auto-on function
The automatic switch-off/switch-on reacts differently depending
on the pre-selected input. If no signal is present at the analog signal
inputs, an automatic switch-off takes place within 20 minutes.
Switching on is reversed as soon as a music signal is detected. At
the other inputs, the activity of the connected source device is monitored
and therefore immediately switched off or on. At the inputs
Spdif, Optical, Port, AES the presence of the digital data stream is
evaluated, while at the USB input the presence of the USB supply
voltage is considered.
Note: Modern computers often have USB sockets with a voltage
applied even when the computer is switched off (e.g. for charging
a mobile phone). If you want to use the auto-on function of your
nuPro active loudspeakers in conjunction with the USB input, you
must select a USB connector that does not have continuous voltage."

@td47: Good morning, thanks for your input here. I checked already out that function before and the function Auto On / Off was always activated. It also works for all other inputs, besides for the "Port"-input. Apparently, here happens exactly what's quoted in the description you copied. The HDMI-ARC adapter seems to get always power from it's USB plug and therefore the Auto On / Off function of the speakers is not working.

However, this goes a bit in a different direction that I was heading to. In my setup, I don't want to rely on the Auto On / Off function of the speakers themselves- I wanted to use the "Magic Remote" and HDMI ARC abilities of my LG TV. There, I would have expected that the TV sends a "Turn Off"-signal via HDMI ARC to the speakers and tell them to shut down too. Same when turning on the TV. And what's still mysterious to me, that it does work during the configuration mode. I can turn on and off the speakers by pressing a button on the TV during the test out phase of the HDMI ARC configuration. However, after completing that configuration, the only function which functions is adjusting the speakers volume with the Magic Remote. Unfortunately, the synchronization of the Power (even with the function activated) remains unfunctional.

Looking forward to any other suggestion.

@JetForce This is an interesting (but complex) issue. I assume that the HDMI CEC channel control (like anynet turn on/off stuff) is done by the LG TV device configurator software/firmware, but it is odd that it only works during the setup and test phase, but fails during normal working. This would suggest that this is either a firmware bug at the TV end, or some complex incompatibility, where a CEC standard has not been fully adhered to on one side (TV or your speakers). My suggestion would be to raise a call ticket with your speaker manufacturer, giving them as much detail as possible, to see if they have any new firmware  in test that might fix your issue. Depending on what they say, you could then push the issue back to LG, with the extra "knowledge" gained from NUBERT, as it could still be an LG firmware bug.

In the meantime, you might want to review the 2 links here, so you can add to your case technically if you need to, and rebutt any BS that either side comes back with:

See this interesting article about ARC, eARC and sound compatibility:

@td47 Thank you for your detailed answers and participation in that problem! For now, I contacted Nubert describing the problem. The really looked into it coming up with the fact, that it is probably a firmware bug in the WebOS. They also mentioned the Auto-On-Off function of the speakers themselves as you already did, and that it also necessary to have connected the HDMI cable to a socket which is not always powered. However, this is a different pair of shoes.

I now opened up a ticket LG support, hoping for them to really have a look into it. I also took a video describing my problem.

Let's see if it helps anything.

      While the appearance of most appliances rarely changes, the television’s aesthetic is constantly evolving through its vibrant display. Positioned prominently in most people’s living rooms, the TV serves as a window to another world, transforming the space into a stadium one moment and providing panoramic views of the great outdoors the next. The atmosphere of the room often hinges on the placement of this essential device.

      To ensure their design complements any room, LG’s latest lineup of TVs boasts a thinner form and slimmer bezels, providing complete immersion whether watching shows, films or playing games. These efforts extend to reducing the number of cables to eliminate clutter and visual distractions around the screen. Additionally, LG has paid close attention to the design of peripheral devices, such as soundbars, to ensure they harmonize with the room’s overall aesthetic. The driving force behind this new design direction is a deeper appreciation for people’s ever-evolving daily lives. Nowadays, people invest considerable time and effort into the layout and design of their homes, often seeking ways to place their TV in locations that better match their lifestyle, rather than simply following its conventional placement in the living room. The TV is evolving in response to emerging trends, more diverse lifestyles and consumers’ changing needs.

      More Thoughtful Living Spaces
      Naturally integrating a large TV screen into its surroundings can be challenging. While most large TVs tend to dominate the design of a living space, a large LG TV complements the interior, adding unique design elements that enhance depth and ambiance.

      The best decorated living rooms all have one thing in common: a TV that naturally integrates with the rest of the space under a unifying theme. To help home designers achieve this, LG OLED TVs fit flush to the wall like a picture frame, transforming the space to resemble an art gallery when placed centrally. These designs utilize the TV as a focal point to set the tone and evoke desired emotions, clearly emphasizing the TV as the ‘main character’ without compromising the room’s elegance and identity. This is why LG emphasizes the ‘essentials’ when designing LG OLED TVs, focusing on the inherent value of the TV in everyday life to create designs that bring people closer to their dream home.

      Seamlessly Blending into Living Spaces
      Today’s TVs must be able to blend into their surroundings. While large-screen TVs often look best mounted on the wall, small and medium-sized TVs can be placed anywhere in the room to match the user’s lifestyle.
      TV stands are providing people with the freedom to position their TVs where design and functionality are maximized. The simple yet elegant LG OLED Gallery Stand1 accentuates content by resembling a canvas on an easel. Similar to the LG OLED Objet Collection Posé, this design frees up space and can serve as a room partition, offering new perspectives on interior design with a back that doesn’t need to be hidden away.
      Flawless Designs Pay Attention to Unseen Elements
      As lifestyles diversify and spaces expressing individuality increase, LG is innovating TVs that consider every design element, even the parts that are normally out of sight like the back of the TV. This helps them blend naturally into any space and achieve an unmatched sense of ‘harmony.’ To strike the ideal balance between elegance and functionality, every ornament and piece of furniture, including the TV, must harmonize under one concept. This desire for ‘harmony’ in the home is bringing exterior elements, such as natural light and natural materials, into the home as if they were seamlessly flowing from the outside to the inside. This is known as the “biophilic” design trend.

      A ‘biophilic’ décor incorporates natural materials like stone, wood and metal while utilizing nature’s most iconic colors and textures, appealing to our innate connection to the natural world. This emerging concept promotes the use of large windows to fill the house with natural light and the ‘planterior’ trend, which employs plants to elevate the ambiance, transforming the interior into a natural space for healing and relaxation. LG’s new design direction for its TVs aligns with ‘biophilic’ values, emphasizing visual comfort in a natural setting.
      To keep pace with these trends and accommodate lifestyle changes, LG recognized the need to focus on details it had previously overlooked. This is why LG has redesigned the back panel of its TVs.
      This image was created to aid understanding
      Inspired by the tranquility found in nature, LG added a rustic sensibility to the LG OLED evo C4’s modern design with the ‘Statement Stone’ pattern. This feature mimics the look and texture of stone, adding depth and elegance to the space, while its natural ‘Umber Brown’ shade reinvents the back panel with a warm, nature-inspired tone. The emotions this design evokes harmonize with emerging trends, such as the ‘biophilic’ concept.
      This image was created to aid understanding
      The stand design, which has also evolved to suit different usage environments, is no different. With stands evolving with new TV designs, LG added a height adjustment function to some stands.2 Although this may seem minor at first glance, its impact goes beyond expectations by allowing nearby devices, such as soundbars, to be positioned in a way that harmonizes with the TV as well as users’ diverse lifestyles.
      This image was created to aid understanding
      The same principles have been applied to the LG OLED M, the world’s first wireless OLED TV.3 To conceal peripheral devices and neatly organize the device’s cables, LG has removed every wire except the power cable with its Zero Connect Box,4 which wirelessly transmits video and audio to keep the area around the TV simple and clutter-free. By implementing a design that considers hidden, easily missed design details, the LG OLED M gives homeowners the opportunity to curate a space for their distinctive lifestyles.
      By aiming for design perfection down to the smallest details, LG is developing TVs that naturally merge with the interior design without losing sight of the essential elements that make a TV so important in everyday life.

      Hello 
      We have an LG55UQ75006LF 2022 model. Until recently we were getting Dolby Atmos on our Creative soundbar. This was via Disney+ as well as numerous clips on YouTube. Now only Dolby Digital plays. We haven't altered any settings, so cannot understand what has happened. There has never been an option for Dolby Atmos in the TV settings, so assume it was some kind of pass through.
      Any advice would be greatly appreciated. Thanks

      On LG OLEDs. You go on and disable SIMPLINK. Fine. But everytime you turn on your HDMI device it enables itself back again. This happens because they have disables two key features that were present in previous OSs, as you can see clearly here
      link hidden, please login to view (they even put screencaps of the menus where you see the missing options in the 23) These functions are Auto Power Sync and Auto Device Detection.
      Man updates are supposed to add functionalities not the other way around. It's very annoying to turn on your TV and have your AVR turn on without you wanting to.

      Anyone found a solution for this problem?

      Hello there,
      Is it possible to turn off search on the home screen, or filter results to show only apps? Ideally, I'd like to limit content to be appropriate for kids.
