Hello DJLION,
Thank you for using the Apple Support Communities. We know it's important to make sure your Mac speakers work as expected. We understand the audio from Apple TV+ has a lot of static, but other apps seem to work as expected. We'd like to see how we can help out.
To narrow this down, do you have a pair of headphones available? If so, test out the audio from that same app with headphones. How does that work?
Also, you could try testing this in a newly-created administrator account to determine if the issue is system-wide or user account-specific. Here's how to Set up users, guests, and groups on Mac. Once you create the account, sign in there to see if the same thing happens, and let us know the results.
Take care.
