So, after the last software update on my LG C9 last week an extremely loud random popping sound comes from the sound bar when streaming from any service, Disney+, Netflix,Amazon etc. \n\nFirst my setup. 2015 NVIDIA shield HMDI to the LG SL8YG soundbar, then HDMI back to C9 over the ARC channel. This set up has been absolutely flawless since September when I bought both units new, until this update. \n\nNature of issue and diagnosis so far. So at first I thought it was just Disney+ glitching out because that's all we were watching the past few weeks. Noise does not occur when using plex or DVR, only from streaming apps. Doesn't matter if your watching them from the Shield or the built in apps on the LG. After starting a movie or show a few minutes later an excruciatingly loud cracking\/popping noise comes from the sound bar for a couple seconds then stops. Then it comes back every couple minutes. \n\nSo, I narrowed it down to the soundbar being set to movie mode on its audio preset. When I change it to standard mode noise is gone. I can't figure out why this is happening and its extremely frustrating because the standard mode sounds so flat and has to be turned up so much, movie mode was perfect for anything we were watching. Any ideas or suggestions are greatly appreciated, thanks in advance!
