game crashing and loss of game sound

im new to PC and ive always wanted to play this game. i have bought
this game and played it a couple of times and its been great but only recently something happens. when i load up the game i get the menu sound but when i enter the menu the sound disappears and in game sound as well therefore i haft to connect my speaker to it again ( worked fine when i was playing it) and then i click the game again and the sound comes back but then it crashes immediately. any other game sounds fine with the speaker and doesn't do it, THIS IS THE ONLY GAME TO DO IT!

speaker: jbl flip 4
gtx 1050ti
amd processor
asus motherboard.

all good stuff inside so please help instead of taking the mick/asking things i probably wont know.

cheers guys
