Just finished, yesterday, migrating from kernel 2.4.26--Mandrake version--to 2.6.4--my version. I'm trying to get my CD player to play on either AlsaPlayer or XMMS. I can play audio files on both of these players, but not CD's.
I learned linux on 2.4.xxx in both RedHat and Linux and had just begun to understand SCSi-Emulation. I migrated to 2.6.4 because of the ALSA drivers and the native IDE/ATAPI drivers.
I may be getting two concepts confused, and, if I am, I would appreciate someone pointing that out to me. And BTW I have "googled" any and all error messages I have received and found noting appropriate, helpful or relevant.
Here is the output of
dmesg with regard to my IDE devices and the versions of things I have in my box
Code:
dmesg

My device is actually a CD/DVD read/write drive and I could possibly not have the correct driver compiled to get to the write functions. Right now, I just want to access it for playing and for files. All of the system information accurately reflects what I know of my hardware.
Back to the symptoms. As I said, neither XMMS (1.20) nor AlsaPlayer will play cd's. When I try to configure the input cd player plugin for XMMS (CD Audio Player 1.2.9[libcdaudio.so]), I point it to /dev/cdplayer,
[cdplayer is a link that points to /dev/hdc. I did this so I wouldn't get "cdrom's" confused.] andw hen I "check drive," I get the error message
Code:
xmms
Failed to open devide /dev/cdplayer
Error: Permission denied
I tried to play a cd in
aplayer from the command line. When I ran it as myself I got told "Permission denied." When I ran it as root I got "Error 1814."
Here's more info to wade through:
Code:
$ ls -alQ /dev/cdplayer /dev/hdc /dev/cdrom /dev/cdroms/
lr-xr-xr-x 1 root root 3 Mar 14 01:13 "/dev/cdplayer" -> "hdc"
lr-xr-xr-x 1 root root 13 Mar 14 07:39 "/dev/cdrom" -> "cdroms/cdrom0"

And finally
Code:

Now that I've bored everyone to death with all the data here are my questions:[list=1][*]If this is a permissions problem where do I change them and to what?[*]If this is a configuration problem, how do I access the CD drive in /dev/?[*]If the problem is neither of the above, I would appreciate any pointers or knowlege anyone wants to transmit.[/list=1]
I also apologize if I provided any extraneous information. I have edited the output of my commands to try to limit the information to only that which is applicable. If someone needs more info, please let me know. Thanks.
