My Media Keys not work (F7 F8 F9) on Sonoma MacBook Pro 2023
After a Reboot the Fast Forward Play/Pause and Fast Backward button doesn't work. Only PP opens the Apple Music app.
Solution:
Disable Siri in Settings -> Siri & Spotlight -> Siri Ask
Check if the Media keys works then enable Siri if wanted.
