Hello all,
Since upgrading to Ventura 13.5, the volume on my 2023 16” MBP’s internal speakers turns way down (for example, from 50% to about 10%) randomly and of its own volition. This happens in Music as well as in Safari when I am playing a video. Also, there is the occasional static record-scratch sounds when, say, I am playing a song in Music but switch to another application. Happens at the moment I switch and then goes away. I have done everything I can think of doing, short of uninstalling 13.5. Thanks for reading and I would appreciate any help!

Have you shut down and restarted more than once since you ran the update...
To trouble shoot further you can:
—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
This test will tell you if third party interference; most* extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
unplug all third party peripherals when testing
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
all known to cause issues on the macOS
