Kubuntu 11.04 was working fine in one AMD64-bit PC. I swapped my hard drive into another PC (HP Pavilion a1012x), and it booted right up and everything works fine!  Except... on the new PC no Device Actions trigger when I insert a data CD, music CD, or DVD into either of its CD-ROM drives.  I don't get the "Available Devices" menu of options to Open with File Manager/VLC/Dragon, and the USB panel icon tooltip says "No Devices Available".  Yet music CD shows up fine in Dolphin, device action "kioclient exec audiocd:/" works fine from the command line, vlc can File > Open Disk > /dev/cdrom1" fine.

I think the problem lies in the Solid layer. Entering `solid-hardware list details` reports

Solid knows there's an Audio Optical Disc in one of my drives, but for some reason it's ignored, and the System Settings > Device Actions rules include "The devices Ignored must equal false". I don't know if the "Advanced probing on /dev/sr0 failed while reading block size" is significant.

Reproducible: Always

Steps to Reproduce:
0. (Maybe have to reconfigure PC with two optical drives ?)
1. Insert music CD or DVD or CD-ROM

Actual Results:  
Nothing happens, no Device Actions.

Expected Results:  
CD shows up in Available Devices and/or with Device Actions.

My problems sounds similar to Launchpad bug 709868 "kde 4.6 device actions broken", he also has  StorageVolume.ignored = true. He comments

    Ok... experimented a bit about how solid-hardware works and found what the latest problem is 
    One needs to create /media/cdrom0 by hand. 
    Solid does not manage mount points automatically creating dirs in media at need 
    Solid does not anymore mount by label... namely should have mounted as /media/CDSTOMPER35 but mounts as /media/cdrom0 

But I have a /media/cdrom which symlinks to /media/cdrom0. I have /dev/cdrom1 and cdrom2 symlinking to /dev/sr0 and /dev/sr1.  Do I need to create a /media/cdrom1 ?

BTW I'm confused what to do with this problem. It feels like it might be a Kubuntu configuration issue, but launchpad says "KDE Base Runtime Bugs are tracked in KDE Bug Tracking System". It seems answers.launchpad.net isn't used for Kubuntu problems. There isn't a Solid forum on forums.kde.org, does this problem belong in Workspace or Appearance & System Customization?

I tried to learn more about Solid, but no matter what link I follow on solid.kde.org, I only ever see its home page. E.g. http://solid.kde.org/cms/1072
