LG Smart TV 2024 built-in Chromecast crashes TV or has Distorted Audio

[herebedragons69]

I purchased an LG 86" UT8050 4K UHD LED Smart TV (2024) from JBHIFI in Australia. The TV was wall-mounted and set up by a local installer. I discovered that my TV has Chromecast built-in. I tried casting music from Roon, but Chrome immediately crashed and the TV shutdown. I tried again and the audio was distorted. I shut down and tried again and the audio stuttered. I tried Chromecasting with Qobuz and Plex and got the same result on audio playing out to my Yamaha RX-V6A and the TV speakers. I then tried to play audio from the Plex App in the LG WebOS. That played fine, without any distortion.

Thinking this might have been a result of a hurried setup (the installer did this job "on the run" I reset the TV to factory defaults and set it up again. Everything went smoothly. But the problem with Chromecast persists. First time launching Chromecast the app crashed and the TV shutdown. 2nd try I got distorted audio to the receiver and to the TV speakers. Audio and Video are fine on all other apps. I can see no other faults.

I've been Googling this and not seeing much info other than a few threads where people are saying that the LG built-in Chromecast feature does not work. I saw that one person returned his TV and the replacement had the same issue with built-in Chromecast. Most discussions on this issue are hijacked by people using a Chromecast streamer or dongle as opposed to the built-in Chromecast. They often talk about turning off this or that specific Chromecast setting, settings that are not accessible with a TV with built in Chromecast

In the WebOs when I look at connected source devices Chromecast is there with a "Chromecast Settings" option. The settings have only one option and that is opt-in on sending crash data to Google. Apparently, Google is not monitoring the issue very closely.

I listen to mostly Hi-Res audio. I wonder if the issue is caused by the bitrate of 24-bit Hi Res flac files. I did notice that when I cast audio that was CD quality (16-bit), the distortion did not occur. This is weird though because in the past I have been able to cast 24-bit audio to Chromecast-enabled devices without any problems.

My TV says my firmware is up to date. I did not see a prompt to install a firmware update during setup. I've set software and app updates to be automatic.

Appreciate any help or even a "Hey, it's not just you, this is a known issue, I've got this problem too".
