Hello, is it anyone here ( or on this planet ) that can help with this issue on Catalina Mac OS 10.15.5 Beta 3 (19F72f).
I am using MacBook Pro 16 inches. 😟
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.
I *really* want to see the flow of audio in macOS, and the changes in gain/amplitude along the way.
If I use the test osc plugin in Logic Pro X, running thru a specific CoreAudio driver, I can succesfully manage keeping a consistent gain structure all the way thru my mixer, using Apple supplied Class-Compliant driver. 0db sine wave is exactly that all the way thru. Easy enough. If I go over that, I hear distortion.
Now... safe to say that's calibrated, but... if I use the Music app, or audio coming from Safari, signal is about 4.5db hotter. That simply *cannot* be right. Send that to internal speakers and of course they're cracking and popping.
