I am hoping to connect my samsung tv to a wireless soundbar, or speaker. The challenge is, i am curious if it can be done wirlessly, and not via an optical cable or hdmi cable.
The samsung tv i have(the frame 55 inch 2018) advertises the ability to connect speakers over bluetooth, and samsung advertises wifi connection for its speakers, but I am wondering if the initial connection between television and speaker can be wireless(and not just speaker to speaker)
