Hello Joachim,

after upgrading to F10, any try to play music CDs fails with each

All F10 updates have been applied.  Somebody made similar
experiences?

When I inserted a music CD in my player, I received a prompt as
expected, opened Rhythmbox, and when I selected "Play" for the CD it
played as expected.  Could this be a specific hardware-related bug?

You don't mention exactly how it fails.  If you could be more precise,
it would help people who are trying to diagnose your problem.




Hi Paul,

Addendum: running rhythmbox under root, cds are played perfectly.
=================================================================

1. Insert the CD in /dev/sr2: the CD icon appears on the desktop.
2. rhythmbox is started automatically: I hear some access noises
    from the
    CD player, then rhytmbox says: "not playing".
    Nevertheless, I can drag some tracks to the desktop by rhythmbox.
3. Having a look in /var/log/messages shows some lines:

ls -l /dev/sr2

When you do the "id" command as your normal user, are you a member of the "disk" group? What are the permissions on the other players, I assume there are sr0 and sr1 devices as well.
