I grabbed a music CD (pink floyd, delicate sounds of thunder disc 2) and inserted it into my hirsute system.
Response was identical to that described by OP, with my GNOME-DISKS looking pretty much identical to the picture provided (excluding red censorship, dvd drive model, size of disc etc or expected differences) I have NOT clicked AFFECTS ME TOO, as I can't a reason why I'd want to mount the drive with gnome-disks. A look at the Github (https://gitlab.gnome.org/GNOME/gnome-disk-utility) says "GNOME Disks, gnome-disk-image-mounter and gsd-disk-utility-notify are libraries and applications for dealing with storage devices." A look at the `man gnome-disks` also doesn't convince me this is something a user should expect. "gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks and block devices." Thus I'll confirm I get the same response in hirsute (3.38.1-1ubuntu1) but I've not checked affects-me-too as I'm unsure it's a bug. If `mounting` is an intended/expected feature it does impact me (but I didn't see reference to `mount` in the man pages, except in the 'see also' section which refers you to other utilities) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-disk-utility in Ubuntu. https://bugs.launchpad.net/bugs/1912536 Title: Gnome Disk Utility can't mount audio CDs Status in gnome-disk-utility package in Ubuntu: New Bug description: 1) Ubuntu 20.10 2) 3.38.0-1ubuntu1 3) Gnome Disks should be able to see an audio CD when mounted. 4) Instead I get "unknown" in the contents and the Audio CD cannot be read. This occurs only in Ubuntu and not in Windows (dual boot). Tried multiple CDs. I also get the exact error on a USB Blu Ray drive.
