Catalina has a big issue with CoreAudio this time or I don't know exactly what it is. But if you are not producing music like me switch it to 48 kHz. I think it can help but is not fix the problem. Over 6 months Catalina is still stuck with this sound issue, especially people like me with brand new MCP16 inches.P.S. I have seen this problem with cracking and popping sound from EL CAPITAN. Every new MAC OS has this problem I don't know what is wrong, hardware, or OS but absolutely every time when the new OS is come out this problem is like some that are created to be like that, always. 😟 But this time it looks very long time to be fixed and there is no solution at the moment.

BTW Catalina Mac OS 10.15.5. BETA 4 still can not fix this issue ... is so important for me... I am music producer and this killed my work....
I am with the beta version of the new os BIG SURE and this new MAC OS still CAN NOT fix this problem with the sound. I already spoke with Apple because I want back my money because this is ridiculous. Super expensive computer with this problem. I've made one Video for youtube 33 min and share all problems with 16-inch pro and Catalina and 265 people around the world contacted me with the same issue. Apple DONT CARE ABOUT THE SOUND and we never gonna see perfectly work machine with this I am 110% sure. Sad but true.
