Hello everyone.
Since getting the ARC, I keep having issues with the ARC disconnecting from any audio sources. I have a LG B9 TV with the latest firmware installed. There were supposedly fixes for eARC on this release. Randomly no matter what the source, the ARC HDMI port will show its disconnected. This causes the audio to kick over to the TV, then about 5 seconds it shows the HDMI port has been plugged back in and switches back to the ARC. Dolby Atmos does work from Netflix, Amazon Xbox1X etc, and it seems like when it is on Atmos it dosent do it at all. Its appears to be only with standard non atmos audio.
I have tried the following:
- Swapped HDMI cables from the ARC to the TV. There is currently a HDMI 2.1 cable plugged in, replacing the stock cable that came with it. To be clear it did it on both the stock cable and the new 2.1.
- Changed audio settings on the HDMI port from the TV. There are only two options per HDMI port. Bitstream and PCM. I have changed the settings for both. It still does it no matter which audio is selected.
- CEC is enabled. I disabled power save options on all devices hooked up to the TV. I thought that the external devices were powering on and off sending a signal to the TV causing issues. I can say it doesn't do it as often now, but its still happening.
- Made sure the ARC is updated with the latest firmware
- Made sure the TV is updated with the latest firmware
- No network issues. I don't think this would be a network problem anyway because its using the HDMI port
Im running out of ideas to try. At this point I dont think its a external problem. Its either a problem with the ARC, or the TV. The fact that it dosent do it when listening to something in Atmos makes it more confusing. Can anyone think of something else to try or have any ideas? Its not the end of the world, but very annoying.
