Often while playing Minecraft ,I have heard block/ambient sounds repeat before the other has completed playing. Such as the same water running sounds playing 0.1 seconds after it starts, creating a horrible sound. This also happens with ambient sounds, such as the warped forest noises playing twice at the same time. I’m not sure exactly how to replicate this, since it is up to random chance, but possibly the code might lack something to tell it not to play that exact sound again until after the first one finished, and to wait a bit before playing that sound again. Block sounds like mining and placing are not the problem, just random sounds such as water flowing/ambient nether noises as an example.
