I've absolutely loved the sound quality since getting this Macbook Pro back in 2019, but after installing Sonoma the music has become all tinny with very little bass.

Any idea how this can be fixed?

Thanks!

Never had this issue and can not reproduce it.

The current stable release of Sonoma including bug fixes, security updates is macOS 14.4.1

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 non-essential peripherals when testing

Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
