AC3 setting not available in Macbook Pro Retina

Can't find and answer to this on the forum. I only see PCM and Stereo on the Audio settings. I've tried several 5.1 videos and setting remains the same even when they play.

Thanks.

Hello everyone, I recently started using Apple equipment, I liked the video reviews on the Internet and decided to buy it. But I really don't know how to use it, can you advise me something?

I take pictures all the time, and this is mixed with important photos, one mess and I don't know how to fix it. I started looking for options on the Internet, I found a post that tells how to properly arrange photos on your phone. I found this post https://macpaw.com/how-to/organize-photos-on-iphone helpful and glad I found it. I hope I'm not the only one and this post will be useful to someone.
