Sounds become glitchy at the end of the game

Hi, I just finished my first match a few minutes ago. When everyone was in our base destroying the main tower, all the sounds started mixing together and became really distorted and annoying.
I have a low spec PC (GTX 1650, 16 GB RAM, i3-9100F), so maybe it’s because of my hardware, but I’m not sure.
