SOLVED - audio cds won't mount. data and dvd are ok
carm25 at Debian forums - I did a dist-upgrade last weekend of my laptop Debian sid system, updating to the getting-close-to-shipping Debian 6.0 ("Squeeze"). I posted then about how I disabled the trackpad, to avoid irritating palm taps. Well, another problem popped up. The machine was no longer recognizing audio CDs. Since that's how I buy most of my music these days, I noticed pretty quickly. The solution that worked for me is at the link. It changes the udev startup code to create some additional softlinks in /dev to /dev/sr0, the CD device. Unlike the author of that piece, however, I had to make the change to the startup file and reboot. Simply adding the softlinks didn't fix the problem.
Make a backup of "/etc/udev/rules.d/70-persistent-cd.rules" I do this by putting a "~" in front and behind the file name letting me know that is the original backup file.
Now you are going to edit "/etc/udev/rules.d/70-persistent-cd.rules" Your file will look slightly different, but look for the block that has "cdrom1" "cdrw1" "dvd1" and "dvdrw1" copy the entire block and paste it just below. Remove the 1's behind "cdrom1" "cdrw1" "dvd1" and "dvdrw1"in the block that you just pasted in. Save the file and reboot your computer.
This is what my file looked like after i edited it, notice the second block where I did all the editing:
/etc/udev/rules.d/70-persistent-cd.rules
