No sound on Samsung smart tv while using screen mirroring with my s4.

[Android Central Question]

I have been using screen mirroring with my s4 for over a year now without any problem. Now all of a sudden either it wont connect to my smart tv or it does and theres no sound. I dont get it, nothing is different, I always update when prompted too. The volume is up. It just wont work and its the only reason I have kept my s4 this long because it works with my smart tv. I have spent too much time on this issue already trying everything that I find on the internet to do. I dont think I should have to add more apps or security to get this working when it was so simple to use for so long. Please help!!
