sound not working with bluetooth accesorys!

i know the ps 3 is quite a goofy and old model but its still fun to play with it. i recently got it from a relative and there was a lot of hella games i didnt even know existed. so i reseted the ps 3 ofc and then proceeded to a game. i actually connected the blueetooth to a speaker and the output and input sound thing and where the sound comes but still no. i tried w my wirelles headphones still no. i need help asap cuz games arent fun without sound
