I know you're becoming weary of this, cause I sure am!
Here's the output of the terminal:
[root@localhost dev]# cd /dev
[root@localhost dev]# ls -l |grep cdrom
lrwxrwxrwx 1 root root 3 2010-04-20 12:20 cdrom -> sr0
lrwxrwxrwx 1 root root 3 2010-04-20 12:20 cdrom1 -> sr1
crw-rw---- 1 root cdrom 21, 2 2010-04-20 08:40 sg2
crw-rw---- 1 root cdrom 21, 3 2010-04-20 08:40 sg3
Hopefully this will give you a clue.
As you can see, I have two optical drives.
sr0 I think is the LG dvd/cd drive.
sr1 is the Sony cd drive.
After sending you the last message, I moved the cd from sr0 to sr1 and
could open it with SMPlayer but not KsCD.
And no matter which drive the audio disc is in, the desktop icon doesn't work.
