Thread: More CD issues

  1. #1

    Unhappy More CD issues

    I've recently installed openSuse 11.4 64bit with KDE 4.6 and that's when the trouble started. If I put a data or mp3 cd in the drive it can be mounted. Simple audio cds refuse to mount, giving me only the option to play on one of the audio players. Since I wanted to move some music to the computer I've had to resort to windows to copy files then transfer them. How can I force KDE/Suse to behave the way I want or do I have to revert to an earlier version with KDE3.5?
    I suspected that System Settings/Removable Devices was where I needed to be but nothing I did worked. So then I tried playing with System Settings/Device Actions and again nothing seemed to work (though the help is pretty obscure as well).
    I can't mount the CD manually,I get this (using su -c "mount etc"
    mount: block device /dev/sr0 is write-protected, mounting read-only
    mount: /dev/sr0: can't read superblock

    I am rapidly getting sick of KDE4 and openSuse and I've been a fan of Suse/KDE for over 10 years

    and, it has changed over those 10 years...used to i had to mount an
    audio CD manually just to listen to it...and if i accidentally forgot to
    unmount it i might have to stand on my head to regain control of my cd
    player.....today i just put the disk in the tray and KDE's "Device
    Notifier" automatically offers me a variety of things i might want to do
    with the disk--"Play with Amarok" or "Play with Kafeen" came by default,
    but if want more all i have to do is right click on the "Device
    Notifier", find the "Device Actions" section and pick from a long list
    of options to be automatically offered...(one of many is "Open with File
    Manager" where you could 'force' it to copy files from CD to hard
    disk....or you could set it to offer "Create file project with K3b" and
    then use that to rip mp3s, or duplicate the disk, or or or or or..

    no forcing and no "sick of" required..

    if you don't like KDE4 then don't use it...i stuck with KDE3 until last
    February and held my nose and moved to KDE4 and have found it to so much
    more capable complete....yep, it requires some effort to learn as lot of
    the capability is in the settings....

    i DO know it is a pain to have something you know and understand ripped
    out from under you and throw you into the land of new (all over again)
    but there it is...

    you can use KDE4, or you can install KDE3, or gnome2 or gnome3 or LXDE,
    or Xfce or or or or

    but, if you wanna give KDE4 a go, have a read or three:

    Audio CDs don't have a filesystem like data CDs. They just contain music tracks. So you don't mount them. If you want to copy them, use a ripping tool.

    hmmmm...i thought i had memories of having to mount them in the old dayz..

    ah! in OS/2 i just put in the disk and it started playing automagically..

    but, Red Hat 5.1 wouldn't....hmmmm, maybe i never got it to play....or,
    when i did it wasn't because i had mounted it..

    Some applications try to make the audio CD look like a filesystem by presenting you with tracks, etc. But it's just an appearance.

    I agree, and I remember with horror things like knowing monitor refresh rates! The problem is that with openSuse 11.2, Ubuntu etc. I could mount an audio CD to see wav, cda etc files. In fact I was very happy with 11.2, but decided to move to 11.4 for a number of reasons. Then it has been one hardware or software issue after another. Almost all are now sorted (though KDE still doesn't quite behave as per the guides), but not the CD one.

    I would prefer not to use Ubuntu or spend time with Pardus, Slackware since I have other things to do, but unless I can sort this out I may be forced to.

    Incidentally, the links don't address the issue of how to reconfigure to get the behaviour you want, at least in this respect. I'd already been through those and more besides. It's been a couple of months now.

    my rule (for myself): Use what works.

    so, if Ubuntu or whatever works for you, have at it! they all cost the
    same (the _time_ it takes to learn how to coax it into doing what you
    want....and then the _amount_ of frustration each new 'upgrade' brings
    as it again requires _time_ to learn the new stuff, and then . . .)

    i booted it (and Debian, and a few others) while trying to decide what
    to do about the death of KDE3...

    now running 11.4 and KDE4 i think i made the right choice *for me*, you
    need to do the same, for you.

    My understanding is that this statement isn't accurate... Although correct that the layout of the content is completely different, any and all optical devices are typically mounted as a loop device. If the content is data laid out on a random access file system, then the loop device is mounted as a "loop block device" which is configured with disk blocks like a "real" physical disk. But, content on an optical disk is laid out differently, instead of blocks, it's a single long spiral from the outer edge to the center of the optical disk. Because data on an optical disk is laid out sequentially, a "streaming loop device" is mounted.

    So, it appears that you did not mount your streaming loop device correctly, your command only mounts a block device. Numerous articles on the Internet should provide complete help and commands, suggest search terms "linux mount cdrom" -- Of course the instructions for mounting a CDROM would apply to any optical device including DVDROMs, etc.

    Skimming this article, I think it should work. Note it
    System Administration : How to use your CD-ROM under Linux

    But, let's also ignore everything above I posted for a moment, it sounds to me from your original post that your device was mounted but you seem to not be able to access the contents of your optical drive correctly. You didn't describe what app you're using to view the files or tracks individually, are you using Dolphin or something else? This sounds to me very much like an application issue and not a system (ie mounting) issue.

    HTH,
    Tony

    That is correct. The Dolphin/Konqueror 'audiocd:/' kioslave can be used to present the CD tracks as files, but the device is not mounted (as a block device) as 'fdisk -l' will confirm.

    I assume that shouldn't be a problem, unless you're trying to write to a non-block device with Dolphin/Konqueror.
    You shouldn't have a problem reading (ie using the optical disk as a source) to copy unless there is a bug in the app.

    IMO,
    Tony
