LG OLED 55C7P Audio Dropouts
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.
