I had Apple Support on the support phone. They are better than Samsung, they find a workaround.
Change your Samsung TV from SoundBar sound source to Television Speaker. After, come back to your SoundBar as preffered sound source. Normally, it works again, sound problem solved.
The full integration of Apple TV 4K not...
The support from Apple was just the best perfect support for that point. They recommended me to contact Samsung Support to have the full correction with Firmware like LG for same kind of issue. It was just a nightmare support... It's like the support of a low cost mark... Never experienced a so poor support like the Samsung Support Customer Experience. I share my experience with Samsung Management.
I'm not sure we will receive a correction from Samsung in the coming days... They say me always Samsung & Apple are not friends... Commercially perfect 👍
