Chromecast 4K, audio randomly cuts out

[LjEntekker]

I experience an issue, where there is a popping sound, and then the audio output from my TV disappears.

The popping sound also comes when turning on and off my TV. 

I just have my TV with the Chromecast 4K plugged in, and no other devices in the setup.

I am unsure where the problem arises from, as I just experienced it again, and it seems that the problem persists, when just using my TVs smart-TV capabilities.

However, when I unplug my Chromecast, and wait some time, sound works again. 

My TV is a Samsung TU55CU7095, and the format for digital audio output is set to "PCM" (instead of Auto), and the TVs setting for HDMI-eARC is disabled. 

The Chromecast is running Android TV OS version 12.

Hope you can help me
