- Why is there always a sound like firecrackers in Cobase?

Sound card buffer has been debugged, 256 buffer is not a problem, why? I’m win10 system, I’m really crazy!

Hi and welcome on the forum,

This is how all DAW work. They need time to process the signal. If you get more time (increase the buffer size), the CPU can process it. If CPU doesn’t have enough time, it doesn’t deliver the result, so you get drop-out.
