Can't play audio cd's

Hungry ghost · 03-09-2005, 08:26 AM

Hi all. I'm using Fedora Core 3, and when I try to mount an audio CD I get the following error:

/dev/hdb: Input/output error
mount: /dev/hdb: can't read the superblock

(Well, something like that, but in spanish). It can mount and read data and mp3 cd's, but when I try to mount or play an audio cd I get this error. The only way to play an audio cd is opening konqueror, then audio-cd browser, but in this way it copies all the songs to the hard drive. Does anyone know how to set my system to automatically play audio cd's??
Thanks in advance.

Pretty nice question.

This is odd, I know, but when I try to mount Audio CD's on my Debian machine, here's what happens:

Code:

xpirokaninjax:/home/stefano# mount /cdrom
mount: tipo de sistema de arquivos incorreto, opção inválida, superbloco inválido em /dev/hdb,
       ou número excessivo de sistemas de arquivos montados

(Translating: "It didn't work").

But anyway, I'm running Audio CD's on XMMS with the "AudioCD Reader" and "CD Audio Player" plugins. But I'm not sure why this happen, maybe the format of the Audio CD or something else.

Audio CD's cannot be mounted because they don't have a valid filesystem. You need to open them using a CD player application like KsCD or GNOME CD player.

If you use digital extraction, use xmms to play Audio CDs. AFAIK it's the only program that will allow digital extraction.

Well, when I try to open an audio-cd using xmms it doesn't find any song in /media/cdrom, and when I execute kscd this is what I get:

"CD-ROM read or acces error (or there's no audio disc in the unit) PLease check you have acces permision to to /dev/cdrom"

Maybe this is due to, for any strange reason, Fedora didn't set my floppy and cd-rom devices to mount on /media/cdrom and /media/floppy but on /mnt/cdrom and /mnt/floppy (which doesn't exist) so I had to change cd-rom and floppy icons mount point to /media/cdrom and /media/floppy so it could read it, but it seems kscd is looking on /dev/cdrom (which doesn't exist either), so I'll look some way to make it look on /dev/hdb.

Also notice that some Audio CDs (original that is) have copy control or copy protection and this usually makes'em unplayable in linux (at least Ive been so far unable to make'em work properly).

Do "#chmod 666 /dev/cdrom" and you should be able to play your CD's.

Ok, I created /dev/cdrom symbolic link which wasn't there, I ran "chmod 666 /dev/cdrom". Now kscd and gnome cd-player read and play audio cd's, but there's no sound (I can play mp3's with xmms and works perfectly). Does anyone know how to fix it??
Thanks in advance.

I finally fixed!! I had to configure xmms cdrom plugin to use digital extraction instead of analogical and to use /dev/hdv and /media/cdrom as cdrom device and mount point. It works perfectly now. Thank you all.
