MrStaticVoid Posted April 22, 2004 Share Posted April 22, 2004 Add 'user' to the options of the fstab entry like: /dev/hdc /mnt/cdrom0 iso9660 noauto,ro,user 0 0 Link to comment Share on other sites More sharing options...
cpugeniusmv Posted April 22, 2004 Share Posted April 22, 2004 open up /etc/fstab in your favorite text editor. look for a line similar to this: /dev/hdc /mnt/dvdrom iso9660 noauto,user,ro 0 0 the first item is the device, then the mount point, then the filesystem type, the options, and i can't remember what the last two are at the moment, but i know they aren't relevant to CD-ROM drives. you will need to change the options section to something similar to what i have: noauto,user,ro. this will make the CD drive not automatically mount at boot-up, allow the user to mount and unmount the drive (if one user mounts the drive, and another user needs to unmount the drive use users rather than user.), and ro is short for read-only.

markwolfe Veteran Posted April 22, 2004 Veteran Share Posted April 22, 2004 Just curious, but those changes don't take effect immediately upon save, do they? How do you get Linux to re-read the fstab? I read the man pages for fstab and for mount (because I thought I remembered something about this in the mount man pages, but I cannot find it now...)

markwolfe Veteran Posted April 22, 2004 Veteran Share Posted April 22, 2004 oro? it's always been instant for me... You are right.. It is effective immediately. :blush: Just tired it. Sometimes it is better to try first, rather than read the man pages, I guess... :pinch: Link to comment Share on other sites More sharing options...
Fozzieb Posted April 22, 2004 Author Share Posted April 22, 2004 hi guys, i have access to drives now but i can't mount if a audio cd is in the drive (can mount a cd or dvd) any ideas? Link to comment Share on other sites More sharing options...
cpugeniusmv Posted April 22, 2004 Share Posted April 22, 2004 hi guys, i have access to drives now but i can't mount if a audio cd is in the drive (can mount a cd or dvd)any ideas? you wouldn't have to mount an audio cd would you? i'm not completely sure...but i think audiocd players just read directly from /dev/hdc ? i could be completely wrong though.

Fozzieb Posted April 22, 2004 Author Share Posted April 22, 2004 when i put audio cd in drive and use cd player it says something about it being wrong file system type or too many devices mounted a bit odd Link to comment Share on other sites More sharing options...
cpugeniusmv Posted April 23, 2004 Share Posted April 23, 2004 hmm, i've never played an audio cd in linux... i'll give it a try :) Link to comment Share on other sites More sharing options...
MrStaticVoid Posted April 23, 2004 Share Posted April 23, 2004 There is no filesystem on an audio CD. It is just raw data. You just play it in an audio CD player. If you want to rip the CD, consider easy GUI tools like SoundJuicer or Grip. Link to comment Share on other sites More sharing options...
markwolfe Veteran Posted April 23, 2004 Veteran Share Posted April 23, 2004 hmm, i've never played an audio cd in linux...i'll give it a try :) Just make sure that, if this was a purchased Windows PC, then you might be missing the audio cable from the CD-ROM to your sound card. Windows uses the CPU to process the sound data. Linux lets the CD-ROM do it's own job of sending audio. This is a common case of "Hey! This worked in Windows, but Linux is broken!". If you don't have sound, pop open your case. Link to comment Share on other sites More sharing options...
MrStaticVoid Posted April 23, 2004 Share Posted April 23, 2004 If you don't have an analog audio cable to connect your cdrom to your sound card, you can play the cd's in xine, mplayer, or a recent version of xmms. Those players support so-called "digital" playback, the way that Windows does. Link to comment Share on other sites More sharing options...

Fozzieb Posted April 23, 2004 Author Share Posted April 23, 2004 It's not the cable issue, it is not reading the cd's no mater what i use to play it Link to comment Share on other sites More sharing options...
markwolfe Veteran Posted April 23, 2004 Veteran Share Posted April 23, 2004 It's not the cable issue, it is not reading the cd's no mater what i use to play it There is *nothing* that should prevent a CD-ROM from playing an audio CD. They have that feature built-into the CD-ROM, itself. If the CD cannot play it, then you have a bad CD, or a bad CD-ROM. Link to comment Share on other sites More sharing options...
jonfr Posted April 23, 2004 Share Posted April 23, 2004 As told here before, audio cdrom only cotains raw data. This might be becose you don't have audio cable. Or the cdrom mute. Link to comment Share on other sites More sharing options...
markwolfe Veteran Posted April 23, 2004 Veteran Share Posted April 23, 2004 It's not the cable issue, it is not reading the cd's no mater what i use to play it Looking over your earlier post, Fozzieb, I am wondering if Linux hasn't possibly assigned your CD-ROM separately. For example, in my grub.conf file, my kernel line looks like this: kernel /vmlinuz-2.4.22-1.2174.nptl ro root=LABEL=/12 hdc=ide-scsi rhgb with the important part being the hdc=ide-scsi part, where it identifies the master device on my secondary IDE as my CD-ROM. Could this cause a problem like you are seeing if the kernel isn't passed this information? Check your grub.conf (if you use GRUB to boot) Link to comment Share on other sites More sharing options...
Fozzieb Posted April 23, 2004 Author Share Posted April 23, 2004 @markjensen I will check that out, about the cable thing, it's not that there is no volume it just wont see audio cd's (data cd's are fine) Link to comment Share on other sites More sharing options...
