Mac mini optical sound output to sound bar

[Cvduring]

I have an old Mac mini with optical output (2014). I would like to connect it to a sound bar but am not sure it will work or be the quality needed for the full audio experience.
I know it will not transfer formats like Dolby Atmos, but I don’t want to transfer just a 2.0 stereo signal. I want to transfer a 7.1 signal for the sound bar I want to buy.
Does anyone have such a setup?

If I recall correctly, you're not going to get a 7.1 signal out of the TOSLINK jack. I believe that it tops out at Dolby Digital 5.1.

Yep, TOSLINK does 5.1 channel DD and DTS max.
