can't play audio CD's


I have been having some trouble with my CD player. I can't play or even mount audio CD's. Data CD's aren't a problem, just audio.
When I try to mount an audio CD, KDE gives me the error:
"Could not mount device.
The reported error was:
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems"
doesn't matter if I'm root or normal user.

Just out of curiosity, I tried to run cdrecord --scanbus and got:
"# cdrecord --scanbus
Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'."
...another error I've never seen before.

I'm running slackware 9.1 with KDE 3.2.2, recently upgraded from RH9/KDE3.1

well first.........you don't mount audio CD's
just put it in the tray>close
and then open up your favorite audio player.......
XMMS, kaboodle, Kscd, etc......

You don't mount an audio cd. That misconception is put down a lot, so don't feel bad.

Tell me, what type of software are you using to play your audio cds? (If you're using xmms you might check the cd audio player plugin and make sure that it's switch to digital audio extraction.)

Also, is your sound unmuted? You might try running aumix to see. Don't forget to save those setting with "alsactl store"

<EDIT>
320mb was quicker than me, so some of my posting is a little redundant.

I *know* i don't need to mount audio CD's...
I loaded the CD in the tray and nothing happened (I'm used to having my programs autostart)... so I launched Kscd and nothing happened.... so I pressed Play and nothing happened... so I thought "that's strange" and decided to try mounting the CD. which didn't work.
the problem is that my system does not seem able to recognize audio CDs. When an audio CD is in the drive and Kscd is open and I press play, it just does nothing. gnome-cd tells me there is a drive error. THAT i think is the problem here, and I don't know what's going on.
oh, the aumix settings look fine.

** (gnome-cd:2943): WARNING **: Error opening CD


...is the error. Other than that, I can't even think of another way to test or diagnose the problem. Anyone got a suggestion?

...which is the same error I get when there is NO cd in the drive. So somehow, my computer has decided to completely ignore audio CD's... is there anyway to make it recognize them again?

Have you tried using CLI cd players?

Have you tried to do anything other than just play music with audio cds, say, have to tried ripping one to a hard disk?

I tried kaudiocreator (The only ripper i know of installed on my system) and it was unwaware of the audio CD.

What CLI players are there? I don't know any so I don't know how to test them.

Try doing this command:
cdrecord -scanbus
Then enter the number it outputs in place of the x's in the next command:
cdda2wav dev=x,x,x

hmm I have already tried cdrecord -scanbus. gives me the same error:
# cdrecord scanbus
cdrecord: No such file or directory. No read access for 'scanbus'.
root@darkstar:/home/solomon# cdrecord -scanbus
Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

I'm running it as root. also gives this error when not run as root.
I just tried logging out and logging into my computer as root... and I can play CDs!!! kscd and all the others work fine!!
but not for my regular account...
what could this mean?

never mind... fixed it... i think. I saw that /dev/cdrom was a link to /dev/hdc and /dev/hdc did not have permissions for everyone to read. I changed that and all seems to be working. I can play CD's again.

new problem:
I can play CDs but can't play mp3's. When I play an mp3 with noatun, the visualizer goes nuts and it *looks* like it's playing, but I can't hear anything. the mixers still look alright, so I'm not sure what's going on now.

... oh btw... I still have trouble with cdrecord. I put a blank cd in and try cdrecord -scanbus and get

# cdrecord -scanbus
Cdrecord 2.00.3 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

what's up with that?

Most things having to do with cdrecord have to be done as root, since the idea of it is to modify a filesystem (blank cd) in a BIG way. The scanbus option is no different, unless the man pages say differently and I'm mistaken.

As for noatun, I've never had any luck with it. I despise it. Have you tried XMMS for all your music needs?

yeah I was logged in as root when I got the above error... i don't know what it is... I can access data from the cdrom, I can now (finally!) play audio from it... but i think I'm still going to have trouble when I try to burn CDs...
what's /dev/pg* anyway? why can't it openthe SCSI driver? what are transport specifiers?

as for the MP3's.. I just tried xmms... it crashed when I tried to play the mp3. So I upgraded to the latest version, 1.2.10, and that crashed too...
/me starting to get frustrated....
