I have similar problem from the very install of KDE 2010 more than a year ago and after that in FullMonty as well.
The CDs I am trying to listen to are burned by myself with K3d audioCD project for my friends.
Banshee and
VLC play audio CD nice but all others don't want at all.
I suppose it is a mounting problem.
Would like to post some observations on trying to play it with:
ClementineMusic-->Open media...-->Audio CD. Click on a .wav file doesn't allow opening -
"
You can only select local files"
AmarokPlay media...-->Audio CD. Click on a .wav file, open file dialog window
disappears but nothing else happens, Amarok isn't freezed.
SMPlayerOpen-->Audio CD. There is CD drive activity and a note at the bottom "
Cache fill: 0.00%". This goes for a long time,
top showing
smplayer and
mplayer eating some CPU percents. I opened once again Audio CD and
SMPlayer crashed,
mplayer still active in
top and CD drive working.
KsCD (a CD player)
Screen showing the tracks name scrolling but no sound (is not muted) and no CD drive activity.
When I am in FullMonty I try other players and they don't play CD as well.
-------------------------------------------------
Opening the CD in
Dolphin and clicking on a file starts some kind of
transfer/copying as shown by Notifications and Jobs in the System Tray. CD
drive active (very active

).
Source: audiocd:/Track 01.wav?device=/dev/sr0
Destination: /tmp/kdecache-<user>/krun/20764.0.Track 01.wav
Sometimes copying speeds are shown and they are very low, often 0 bytes/s, though CD drive is working hard and could work for days if I don't stop it.
/media/cdrom is empty,
/mnt/cdrom doesnt exist.
fstab says
/dev/sr0 /media/cdrom auto umask=0,user,iocharset=utf8,ro 0
mtab doesn't list cdrom or /dev/sr0 or related when CD is opened in Dolphin or is played with Banshee.
Have no problems with data CDs and with the drive itself.
