LG Old loses Audio when switching inputs

I have an LG OLED55C7. I am using 3 HDMI inputs that include: Directv, Apple TV, and a Sony Blu-Ray player. All has been fine for months. Now when switching inputs I lose audio to the input I've gone to and previous input. No audio through internal speakers and Yamaha Sound Bar. If I make a few more input changes. Audio comes back. Also, if I use TV's soundest, audio will return. I've switched cables between Apple TV and Blu-Ray player and still lose audio. Thanks for the advice!

When you call it I hope they review FIRMWARE VERSION and settings but if they don't ask them how to check if the firmware is up to date. They also should have you do a factory reset. Again, follow their instructions. If they can't resolve it, they should offer a service call. If they don't, ask for it.

If they can't resolve this on a new set, you may be looking at a return as defective.

-> ONE LAST THING. Sometimes the handshake is lost or there is an audio encoding problem. For the source that loses audio I always try setting that source to PCM or Stereo to see if the problem vanishes.

Software problem as per LG

In reply to: LG Old loses Audio when switching inputs

I just faced the same issue. After going through LG customer Service who had me do a hard reset, I talked with LG VIP care who told me it was a software issue which is affecting all 2017 LG TV's .. Will issue an update in 2-3 weeks.

Same Issue

In reply to: Software problem as per LG

I called LG support last night and they knew nothing of the problem and simply said if updating the software doesn't resolve it we will have to send someone out. No mention of an update coming...but it wasn't VIP care either. Thanks, I hope this is true, the set belongs to my in-laws and it's making them very anxiety ridden!

The update was not found by the TV, it had 04.70.07
I downloaded from the web and did a hard install with a USB drive inserted into the TV, it did the rest.
make sure you put the file in its own folder labeled LG_DTV.
YOU MUST DO THIS, it won't see it otherwise.

This update solves the problem.

I’m losing audio too

In reply to: 04.70.36

I have 4.70.30 installed.

I’m losing audio sometimes when switching inputs.

I have HDMI sky, Xbox, PS4 and Apple TV. And optical out to Bose Soundtouch. When I switch between inputs sometimes to audio is lost and I can’t get it back. I have to force the source unit to switch audio modes (eg switch from Dolby to Dts or pcm) to wake the sound up.

Really annoying. Anyone got a fix?
