Music app CD import error "Access to the source volume was denied"
When trying to import a CD into the Music app on an iMac running macOS 15.7.1 Sequoia, I am getting the error message, "Access to the source volume was denied. Check the System settings for removable volume access." The prescribed fix (opening System Settings > Privacy & Security > Files and Folders > Music and making sure Removable Volumes is turned on) DOES NOT WORK. Neither does any combination of turning it off/on, rebooting, and turning it on/off.
This is the same problem reported by another user in post 256037665 dated April, 2025. Unfortunately that thread was closed without a workaround or solution. However, there have been several upvotes for the question and over a dozen "Me Too" clicks, so obviously multiple users are (still) having this problem.
Does anyone have any ideas for something to try? At the moment, I am utterly unable to import any audio CDs into Music.
iMac 27″, macOS 15.7
