LG OLED 55C7P Audio Dropouts
Hi.
I've had a 55C7P since early November and I continue to experience very brief (~ 1 second) intermittent audio dropouts when watching cable TV shows and during streaming videos from Amazon Prime. The picture is not affected when the sound drops out. This does not appear to happen when watching DVD's or streaming video from iTunes or Netflix. It definitely does not happen when streaming music from Pandora via Apple TV 4K.
I've switched out cables to no avail. I have isolated the problem to the TV rather than to ancillary devices.
I was told by LG that upgrading the firmware to version 40.70.36 should solve the problem - but it has not. The new firmware does appear to have fixed a problem wherein I couldn't always get audio from streamed movies that were in Dolby Vision or Dolby Surround format, but I'm still getting the random audio dropouts.
I'm wondering if anyone has any observations or suggestions.
Thanks

So far my only "solution" is to not stream with the B7A and use my PS3 connected to the receiver. As the PS3 does neither 4k nor any of the nifty things the B7A is capable of visually, this is not an "acceptable" long term solution.
An update - starting to drop out for a longer time. When I hit skip back button on remote and jump back ten seconds the sound is there.

I just switched soundbars from one with HDMI switching (hooked up to LG HDMI 2 ARC) to a soundbar with no HDMI at all (just optical out from the LG used).
I had no audio problems with the first soundbar - and I had used both HDMI ARC and Optical out from the TV to the soundbar. However, when I switched to the soundbar with only Optical, that's when I started getting 1-2 second volume reductions.
I'm experimenting with the sound settings on the LG....just changed to AUTO instead of PCM
I do not get dropouts when the audio is stereo or played through internal speakers and I do not get dropouts when playing Dolby Digital from the TV's internal Netflix app over optical to my receiver.
Here is a sample of the sound dropping: https://www.dropbox.com/s/amgs9uneyutvqby/Video 2018-04-28, 12 03 16 AM.mov?dl=0

Running the cable box through the receiver stops the audio drops but messes up the remotes such that nobody else can figure out how to use the setup and the receiver won't do 4K with the Apple TV.
Running the sounds over ARC doesn't work either because the Netflix App sends some weird Dobly Digital Plus signal that the receiver cannot decode.
This is driving me nuts and warranty is running out.
Any updates or suggestions?
Thanks.
Is the only real solution to abandon using the LG apps and use an external device like an Apple TV? I have the latest firmware, and if this is indeed an LG issue, it's still not resolved in Dec 2018.
I'm at a loss on what to do. LG wants me to take it in to have my board examined, but that'll likely cost $200-$300. My wife wants to know why we can't just buy a cheap Costco TV to replace it. I'm frustrated. A 16 month TV shouldn't be having these types of issues.
Has anyone resolved this problem?
They really need to fix this and hopefully they can via the firmware.
To get around it for now, the analog out does not have this issue. But be sure to set the TV to "Wired Headphone" and not line out which will allow you to turn the volume down to around 65 otherwise the signal clips. ugh.
