I have a MacBook Pro (16-inch, 2019) running MacOS Catalina 10.15.6. Ever since I updated from MacOS Catalina 10.15.5, when I play music on my MacBook speakers, after a few minutes I'll start hearing a horrible distortion noise along with the music. See https://imgur.com/a/0mK6ciP for a video I recorded of the problem.
I'm able to temporarily resolve this issue if I plug in my headphones and immediately remove them (as shown in the video), or if I go to System Preferences > Sound and change the "Alert volume" value. But then after a few minutes, the problem recurs.
I'm getting the impression this is software-based, and it's not clear to me that the upgrade to 10.15.6 is the cause of the issue. Is there a way I can prevent this from happening?

Can you report there as well https://discussions.apple.com/thread/251560058? You are not the only one.... My guess is that it is not the sound card as headphones work fine, but could be a driver / compatibility issue with the speakers. Def looks like a driver/OS not working as expected to me My issue happened with the exact same version: MacOS Catalina 10.15.6
