Gnome Disk Utility can't mount audio CDs

[Frank]

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.

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)

Note: Audio CD's don't have a filesystem and don't mount. I don't use Gnome or Gnome Disks, so I can't tell you whether this is expected behavior for an audio CD or the program should offer more info about the disc.

At one time, gnome-disks or gnome-disk-utility did detect audio CDs. I just fired up Linux Mint 20.1 on a USB flash drive and whatever version of gnome-disk-utility it has, it shows "Audio CD" instead of "unknown."

[Daniel Letzeisen (dtl131)]

Hmm. Your screenshot shows the program says "Media: Audio CD-ROM", so it obviously understands there's an audio CD in there. Other than saying 'unknown' instead of 'Audio CD' in the picture bar, is the functionality of the program affected in any way?
