I modified the code to see if I can help...

-       {
-               kdDebug(7117) << "cdda_open failed" << endl;
-               error(KIO::ERR_CANNOT_OPEN_FOR_READING, d->device);
-               cdda_close(drive);
-               return 0;
-       }
+//     if (0 != cdda_open(drive))
+//     {
+//             kdDebug(7117) << "cdda_open failed" << endl;
+//             error(KIO::ERR_CANNOT_OPEN_FOR_READING, d->device);
+//             cdda_close(drive);
+//             return 0;
+//     }
 
        return drive;
 }

And I installed the new kio_audiocd.so in /usr/lib/kde3.

The behavior is different, but similar.
/dev/cdrom is accessed (open/close) and the music playing stops !
I tested like this :
- start playing with kscd 
- verify that there is no kio_audiocd.so running
- verify /dev/cdrom with lsof: only kscd currently open it
- lauch konqueror and go to "storage...", press "refresh"...

Before my modif, openning konqueror would have stop immediately the CD.
With my new kio_audiocd.so, the playing don't stops when "storage" is openned.
It takes a little time to display the list of storage devices... Pressing "refresh" multiple times finaly display all devices and stops the CD.

kscd       6359 michel   10r   BLK   3,64      2148 /dev/hdb
kio_audio 19946 michel   11u   BLK   3,64      2148 /dev/hdb
kio_audio 19946 michel   12u   BLK   3,64      2148 /dev/hdb
kio_audio 19946 michel   13r   BLK   3,64      2148 /dev/hdb

Another time, the CD don't stop after multiple refresh presses but after 3 min of playing...
