[PC] No sound/ Subtitles too fast

I am running Borderlands 2 on Win 10 with an AMD CPU and a GTX 550tx.
I have no sounds whatsoever and the subtitles go away way too fast.
I googled a lot and reinstalled the game twice.
After the first reinstall I at least had my subtitles ok but after I closed the game and started it it was bugged again.
I don’t care too much about the sound, but I really want the subtitles.
Someone has a solution?
