Which do you want to use Screen Mirror or Samsung DeX? These two might look alike but have different fuction.

The Screen Mirror literally just copies your phone screen to your television. It needs not any cable to connect.

The Samsung DeX is connects your smartphone to your tv or monitor and turns it into a full fledge desktop PC. It requires a special cable to connect or wirlessly (Note 20 Series).

When connected to your phone there is an Option on your Notification Panel where yout audio will be coming out. Whether phone or the television/monitor. 😊

I believe all S, Note, and Fold series from S10 and up, as long as they are in OneUI2.5 can wirelessly do the SamsungDex.
