This problem wasn't happening a month ago.
I've already tried to change some CPU settings, as well as changing in-game video options to the lowest possible values. I've also tried changing the sound sources under audio settings to all values.
I know other people have been having this issue, so I doubt it is related to my PC specs. Anyway, if you need it, here it is:
Graphic Card: NVIDIA GeForce GTX 650 TI 1GB
CPU: Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz
Memory: 8GB RAM DDR3
OS: Windows 10 64-bit
