These sounds can usually be divided into the following two types:
One is the random crackle distribution, the most likely cause is the software parameter setting. Increase the cache size should be able to get it.
The second is a rhythmic crackling sound, such as a crackling sound every half a second, which may be caused by damaged sound card or the driver is not installed correctly.
Solution:
Such crackling noises are often caused by incompatible software or drivers of the sound card. For example, the Buffer Size is set too low, Bluetooth or wireless devices are connected to the system, or the software compatibility is poor. You can check the content of the software compatibility of the sound card on the official website to see if your computer does not meet the minimum requirements for the sound card.
If this type of noise is heard from your speakers, you can try unplugging the speakers and connecting them to headphones to determine where the noise is coming from.
