No audio - TV stops outputting audio after updating to firmware release 04.70.07
I am having an issue with my OLED65C7P-U. I can consistantly reproduce this problem. Any input device that sends digital 5.1 or higher audio over HDMI to the TV will cause all the inputs (including the built in Netflix, Amazon, and Hulu apps) to stop processing audio when you switch the input to a new device. The only way to temporarly fix it is to run the Sound Test under the sound menu on each input. I have been dealing with LG for a week on this issue and no one seems to have an answer for me. This does not happen when you switch from a device that is only outputting PCM stereo over HDMI. We need this fixed ASAP LG!
Firmware 04.70.07
Nothing fixes this problem, factory reset, unplugging for a day, nothing.
This issue just started with this recent firmware release 04.70.07. LG please release an update that fixes this issue.

Same tv, same issues. Actually returned first tv to Best Buy and second tv did same thing. I was troubleshooting and found unplugging tv and replugging it would return sound. Then discovered sound test which made it a bit easier. Switching between hdmi inputs with remote triggers sound failure but I was able to get sound back by going to hdmi 3 first then back to 1 or 2. Still not happy. Jim
LG please acknowledge this issue and let us know you are adequately prioritizing and working on a firmware fix to be rolled out as soon as possible. Everything else about this TV is fantastic, but this is certainly disappointing.
I'm still getting a bit of a runaround on this from LG but planning to try optical tomorrow and escalate from there. I do have a case open and it seems this hasn't been widely reported (yet).
Out of curiosity which brands of AV Receivers are you guys using/having problem with? I've tried two Sony STRs and have the same issue on both.
We have a brand new (1 week old) OLED55B7 TV and a SH4 soundbar connected to it. We have the TV connected to the soundbar by optical. A SKY satellite box is connected to the TV’s HDMI2 port. The problem we have is that when we turn the TV on we get no sound (the TV defaults to HDMI2 – the SKY box). The SH4 soundbar shows “OPT/HDMI ARC” in the LED screen. We have to change the source to either Live TV (Freesat) or Netflix (both of which have sound) and then change back to HDMI2 to get sound working on HDMI2 (the SKY box). We have connected the SKY box to the TV with a brand new high speed HDMI cable to see if that cured the problem but it doesn’t.
I suspect that this where they broke it.
LG, are you listening?
Whether or not there are other issues will take some experimentation... but this update was welcomed!
