CD mount fails and sound is not working


Hi all,
I am new to Linux.I have already managed to install RHL 7.2 and managed to run X windows on a SIS 6215C graphics card.Now I want to install Java 1.3 for Linux.But when I try to mount the CD using /mnt/mount cdrom the error that returns is special device /dev/cdrom does not exist.

Also I have ESS 1869 audio driver which Linux has detected during install but I am not able to play sounds from my Linux environment(GNOME).Can you please where's the problem and how to solve..

Thanks in Advance,

Sourav

When I have installed Linux,KUDZU detected the ESS 1869 sound card and configured it.Do I need to do anything else after the installation ? if yes, what is that ?

Does it look like it's playing sound, or does it give you an error message?

Also, the command would be mount /dev/cdrom /mnt/cdrom or something like that rather. Let me know if that works.

As for sound, you may have to open your sound mixer and make sure volume is up.

/dev/cdrom is a symbolic link to the actual cdrom device. You need to know what device your cdrom is to create the link. Is your cdrom on the primary or secondary ide channel and is it master or slave? Then you can run the command
ln -s /dev/hd? /dev/cdrom. Replace the ? with the correct device letter.

Also, you'll want to check your /etc/fstab file to see if you have an entry for your cdrom drive.

It might look something like this:

/dev/cdrom /mnt/cdrom iso9660 ro,user,noauto 0 0

linuxcool=much more helpful advice

And to add to his/her much more helpful advice, the ? will probably be 'c' if it's your first cdrom and is on the second ide channel. Not that that is anywhere near as helpful as the rest of his advice.

Linuxcool, I had no idea that /dev/cdrom was just a symbolic link. That's cool, thanks. And I have been spreading a rumor that 'user' in the options section in fstab means that any user can access that device, is that true?

re-configure

I had the same prob with sound.
to fix you have to go onto control panel and tell the hardware manager to re configure the sound card

not necessary configure, sound isn't started by default in many cases, it could be that it just wasn't started

Try playing sound as root, if it works then you have to change permissions, chmod 666 /dev/dsp /dev/sequencer /dev/mixer /dev/audio and then it should work for users too. If you can't play sound as root you need to reconfigure your card, and load the correct kernel module for it.
mount /dev/hd? /mnt (replacing ? with correct letter, usually c) should mount your cd under /mnt
/etc/fstab cdrom entry shoul look something like this:
/dev/hdc /dvd auto defaults,noauto,user 0 0
replace /dvd with your mount point, noauto means that it will not be mounted automatically by kernel aoutmounter at startup, user means that common users can mount it, by default only root can do that. If you add ro as well then it will not display the annoying "mounted read-only" message when mounting.
Hope that helps

CDROM/DVD Hell

There are 2 of us who went and purchased Suse 8.0 and to get it to install the CDROM and DVD devices. We have been Windoze junkies and thought it was time to boot (no pun intended) Bill G. But.....never did I expect that to install a cdrom or dvd would take all day looking at this forum trying all sorts of things to get this dumb thing to work. So someone in Suse a land or Redhat land needs to take a look at this and figure the mess out. I have rebooted reinstalled more than a dozen times to see if these idea posted here or elsewhere works, tried many of my own....noworky....no shirty

It would be nice to have the media devices including the floppy automountjavascript:smilie(%27%3APengy%3A%27)

Yes, ' user ' allows any user to access the device. An example would be a windows partition that is not mounted on boot up. A user could mount it and access its files and when done, unmount it. While the partition is mounted, anyone else could also access the partition. They wouldn't be able to unmount it. Only the user that mounted it and root would be able to unmount it, but only if it's not busy. Other users accessing the partition could tie it up and it won't be possible to unmount it until they are finished.

There is also the ' users ' option. This allows users to mount and unmount the device. One user could mount the device and another user could unmount it. As, long as it wasn't busy.

If the devices are mounted on boot up, ' user ' and ' users ' allow users access to the device. I don't think they can unmount it. Only root probably could unmount it.
