When I load a commercial cd in Debian XFCE it plays just fine. When I load a cd that I recorded I get an error message. mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.

How did you create the recorded CD?
What operating system?
What type of CD? Audio or data?
What type of audio files?

Recorded using Brasero on Linux Mint mp3 music cd's Plays commercial data and audio cd's okay

Basically you create a data CD and add the MP3 files.

I assume they play from the hard drive ok

Everything plays fine from the hard drive, just not the cd player. You seen the error message I posted? I have tried two different cd play programs sound juicer and quad libet and neither one will play cd's. I may be missing some codecs or libraries? I can play and listen to youtube videos and any other mp3's or other filed online. They just won't play on my cd player in XFCE. They play fine in Mint and my car cd player.

This is a shot in the dark, but did you create a data CD, as michaelk suggested, or did you use the "Create Audio CD" function (whatever Brasero might call it)?

I created an audio cd. Took OGG files and converted them to mp3's and burned the cd's. They are audio mp3 files, not data. I know how to burn audio cd's. As I stated they play fine in Linux Mint and my car cd player, just not on XFCE. I am missing some files or some codecs.

mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error

this is not a codec related error message, but a [most probalby] useless CD. Either the CD itself is broken or the reader went wrong.
How old is this CD reader?

The files on the hard drive play fine on which system? Mint or debian?
There is no such thing as a audio cd of mp3 files.

An audio cd does not contain a file system and can not be mounted. The player accesses the drive directly and according to wikipedia sound juicer versions 2.12+ can play CDs. It looks like debian is trying to mount the audio cd.

Okay, so you are telling me that I have multiple bad cd's that play fine in my car stereo and played fine on Mint but won't play on XFCE? You asked me originally if I was trying to play a data cd. They are music cd's loaded with mp3 files. I guess I am having a bad dream because we are going around in circles. My XFCE distro will not play mp3 cd's so I figure I am missing codecs or libraries.

if you put mp3 files on your CD: this is not an audio disk, but a data cd. You need to have a player which understands the mp3 (usually all modern players know). There should be no codec problem at all. Also would be nice to know how did you burn that CD, some software will automatically convert mp3 files to create an audio CD.
As it was mentioned, you cannot mount an audio CD and you can play it without mounting. But a data CD must be mounted, otherwise the content is unreachable.

XFCE is a desktop environment, not a player.

Never mind. I have answered everything over and over to no avail. I know XFCE is a desktop environment, I am not a total dumbass. I have told y'all over and over that my mp3's play just fine in Mint but not XFCE, which are both desktop environments, I understand. They play fine in my car mp3 player and play fine in Mint Linux but cannot play the same ced's in XFCE, which I also know is not a music player. What do you not understand about what I am asking? Does anybody on here know of an answer to the problem? If not I will go away and not bother y'all anymore.

I am trying to establish an understanding of how you recorded the disks and what you posted. We are going in circles because you do not understand the questions and we do not understand the answers.

A true audio cd conforms to the red book standard. It is not a data disk nor does it contain mp3 or any files of any sort. An audio cd trying to be mounted would produce a similar error. Modern car cd players can play both a true audio cd and a data disk that contains mp3 files. Again they are not the same.

Here is a audio disk

Here is a data disk.
https://en.m.wikipedia.org/wiki/ISO_9660

I have not played audio CDs in a computer in a very long time. Some systems would use a virtual filesystem that would display the audio tracks as either wav or mp3 files in the browser. I don't know if xfce has that capability.

I have not played with debian xfce in a bit so not sure how it works any more but when I have time I will see what's going on.

When a true cd is created you might pick mp3s but they are converted and written as a PCM stream as explained in the wikipedia page.

Mint is a distribution of Linux, XFCE is a desktop environment. Neither are relevant to playing a audio or data CD. You can play a CD with no graphical interface.
How you burned the optical disk. An audio CD or data CD, or some kind of hybrid. What did you burn it with? What burning tool?
Of course not. XFCE is a desktop environment, it doesn't have anything to do with playing optical media.
Yes, mp3's are audio. An audio CD has pcm audio. It is on the disk in tracks. A data CD has an ISO9660 file system on it. I think that you can put a UDF file system on it too.

Are you going to tell us what media player that you are using?
You can play and audio cd with
Lots of other media players can play audio disks as well.
Stop trying to mount it. If it's an audio cd with uncompressed pcm audio on it....play it.

If you have some kind of weird hybrid mp3 "audio cd", you'll need to find out how it works.

libmp3lame is what is needed for mp3 files.

Audio CD's cannot store either .ogg or .mp3 files, they need pure audio tracks (as a continuous stream, there are no separate files on an audio CD, although there can be a TOC - Table of Contents).
On the other hand a data CD-rom (normally iso-9660 filesystem) can store separate files in any format you want.
CD-rom's can be mounted, pure audio CD's canNOT, they are only accessable by an audio player (raw format).

And XFCE is probably using a pure audio player instead of i.e. mpg123 on that CD-rom.
