No sound coming from my sound bar in my Apple TV. 4K.

I have a Samsung TV crystal Uhd with Apple 4K box. I recently got a Samsung sound bar. When I first hooked it up, always sound never a problem. Then I went away on vacation for about three weeks. I come back to no sound. Frustrated as heck, taking an entire day to try to figure out the problem. Still no audio. I unplugged it and left it overnight and next day I had sound. I have the software version 18.0 at this point. Once again, I didn’t watch TV for about a month and once again, I have no sound. I’ve unplugged the Apple TV fittled with the settings still no audio. I updated my Apple TV to the 18.1. Still no sound. What is going on and how do I fix this problem? Because every time I contact Apple I get zero help. I’ve seen a lot of these problems in this thread but they’re all from 2022 and 2023. Has anyone recently still have this problem? Ive followed all the posts and trying to adjust any settings that worked for others with no luck. Do i just leave my tv on for a week and hope to get audio back? I dont even have the audio at the menu.
