Can't Play Audio CDs
Using Fedora Core 3
on Sony Vaio Laptop
Thanks to all who help in these forums...
After fresh install of Fedora Core 3 (Along with the Autorun utility that automatically mounts CDs), I can't play Audio CD's KsCD gives error message:
CD-ROM Read or Access error (or no audio disk in drive).
Please make sure you have access permissions to:
However I don't have a /dev/cdrom file. The systems mounts data cd's fine. So issued the comand:
$ dmesg|grep CD
hdc: UJDA730 DVD/CDRW, ATAPI CD/DVD-ROM drive
hdc: ATAPI 24X DVD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.20
when issue a mount command from the terminal, i get:
$ mount /dev/hdc
/dev/hdc: Input/output error
mount: /dev/hdc: can't read superblock
Here is a listing of fstab:
# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/ / ext2 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
LABEL=SWAP-hda3 swap swap defaults 0 0
/dev/hdc /media/cdrecorder auto pamconsole,ro,exec,noauto,managed 0 0
/dev/fd0 /media/floppy auto pamconsole,exec,noauto,managed 0 0
Anyhelp would be greatly appreciated. Thanks.
Configure your CD drive device in KsCD to be /dev/hdc instead of /dev/cdrom (it's under Configure, under Extras).
Alternately, you could log in as root and make a symlink from /dev/cdrom to /dev/hdc
ln -s /dev/hdc /dev/cdrom
The latter method may save you additional headaches in the future, since a lot of programs assume that such a link will already exist (like KsCD, for example).
Also you may need to give yourself read permissions to the CD drive e.g.
#chmod a+r /dev/cdrom (or whatever your cd drive is)
Configuration and link NOT saved
Thanks for the reply guys. However, when I do those actions, after a reboot, it looks as if I never made the changes - the link is gone and the permissions to /dev/hdc are back the way they were. Does this have something to do with the fstab file maybe (forcing) certain options on the CDROM drive. I started a new thread in the software section, because I thought that it might be a KDE or Fedora issue. Any ideas would be greatly appreciated.
here is the link to the new thread if you want to post there
Try putting yourself in the audio and cdrom groups.
Thanx reddazz. I will try that. I didn't know those gorups existed. Just curious (new to Linux): How do I find a list of all the groups there are? (and what are they for)
You can use a tools such as kuser or gnome system tools. Alternatively you can just do
a list will be printed on the screen. To find out what groups you are in, you can run the command "groups" in a console.
groups do not exist
I think we're getting closer. The only problem is that I don't have audio or cdrom groups. One interesting thing is that when I log on as root. CD's play fine. I anticipate that I need to be a member of one of the groups that root is, but I want to be sure of which one so I don't screw anything up. Here is a listing of /etc/group
Thanks again for all your help.
Well it works good being a member of group disk; but after I'm done playing a CD and put in a data CD, i can't mount it - some error like /media/cdrecorder is busy. Weird... I have to reboot to get it to work or in some cases, just wait a random amount of time (over 10 minutes). I know I'm dragging this out from issue to another, but I've already learned alot. Thanks so much reddazz (and the rest of you).
That sometimes happens to me on my Slack system, I have to wait a few minutes after ejecting a cd from my dvd drive before the system recognises that it's empty. I don't know what causes this.
Are you running KDE on your slackware? Have you noticed if it happens in X, GNOME, or only KDE? Thanks for all the help by the way. Being a member of group "disk" was all it took.
I run KDE, on my Slack box, but occassionally use Fluxbox or Windowmaker. I am gonna try it out in a console session as well as Fluxbox and Windowmaker, to see if it makes a difference.
I'd be interested in knowing how that works for you...
WHat is Fluxbox and Windowmaker?
I've only heard of X, GNOME, and KDE.
been a great help
you've been a great help, thanks. I ended up trying out Mandrake 10.1 and really like it - no problems with the CD stuff. Thanks again - I really learned alot.
