After updating my TV (OLED65GXPUA) on August 31, 2020 the HDMI-ARC volume support changed: pressing the volume up/down button once on the magic remote will continuously apply volume changes until the volume has reached the maximum or minimum value. Prior to this update volume changes over the HDMI-ARC interface behaved as expected: one press of the remote button would apply one increment or decrement to the volume. A Klipsch Bar 48 is attached to the TV over the HDMI-ARC interface.
After the update the TV is running: webOS TV version 5.1.1-3701, Software version 03.10.41. I do not have the version information prior to the update.
I'm new here hoping to find a solution to my problem, after now trying around for almost two days without any result.
- 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!
I've a strange issue that I've been struggling for a week. I bought an LG43UJ634V UHD TV and an LG LHB645N Home Theater in a Box system.
I use HDMI ARC to connect the audio from the TV to receiver. LG has an option to chose between PCM or Auto at the Digital output settings.
If I use the PCM option everything sounds great, but I don't have 5.1, only 2.1.
And here comes the problem. When I choose Auto, 5.1 is on, sounds great but I have occasional popping noise (like when play something on an old LP player) it happens random, but for example during a film, it is very annoying. It happens with YouTube, Netflix, DLNA streaming, external devices, so the content doesn't matter. I think I've tried everything. I tested it with different HDMI cables, optical cable, but still have the problem. I tested it with a sound bar as well, the problem is the same.
When I play content from the receiver, there is no problem, the sound is wonderful, no popping. Also, the TVs speakers are okay.
I don't think it is a hardware issue, because the TV's sound is OK, the home theater's sound is OK, the problem only happens when I want to use the digital output of the TV (either HDMI ARC or Optical) with auto setting.
I called LG as well, the rep. said the she will pass this info to the technical team.
Do you have any idea, that it can be solved, or I need to wait for a software update?
