I don't think so Ed. I just tried it out with my cdwriter and I can play audio CD's OK (When I say I can play them. I did not go so far as to open the case and move the audio cable, but I can eject them, and when I press the play button it looks as if it plays, and the CD light comes on) All I had to do was make my symlink between /dev/scd0 and /dev/cdrom (That's what I said to do yesterday, but not in my last mail) Now Steve your /dev directory probably looks different to mine because I am not using the devfs system which automatically sets up the /dev directory on boot. If you are using devfs you will not have a /dev/scd0 entry. Instead you will have (If I can remember correctly) /dev/scsi/device/lune/target blah blah blah You should make your symlink between /dev/cdrom and the device at the end of that scsi chain. The reason I am not using devfs is because my CDwriter will not work with devfs enabled. Have you tested your CD writer yet? To test it, as root type 'cdrecord -scanbus' If it discovers the SCSI address ok then you do not have to disable devfs If it comes back with an error message you need to disable devfs. To disable devfs edit the file /etc/lilo.conf where it says "devfs=mount" change that to "nomount" Then rerun lilo with the command as root /sbin/lilo (check there are no error messages, or else you will not be able to reboot) Reboot. Now the structure of your /dev directory will be different, and there will be a device called /dev/scd0 There will also be hundreds of other entries for non existent devices. Now check you can mount data CD's, test cdrecord, and try audio CD's Derek > > On Saturday 24 November 2001 04:31, you wrote: > > Steve > > Most of us have no trouble playing music CD's, so we must try to identify > > what is different about your installation to the rest of us. > > > > First of all be assured that music CD's DO NOT have to be mounted at all. > > They do not contain a 'file system' as such.
