Estou com o mesmo problema, só que é mais específico: no ubuntu 9.10 o dvdrw funcionava, agora no 10.04 e no 10.10 tudo funciona menos "cd normal de áudio", quando coloco um no drive aparece:
Não foi possível montar Disco de Áudio: A localização não está montada.
Praticamente todos os programas que tocam cd não funcionam dando erro de montagem/localização. Já cds como o do ubuntu funcionam normal, assim como dvds e afins.

alessandro@alessandro-Ubuntu:~$ sudo mount -t iso9660 /dev/sr0 /media/cdrom
mount: dispositivo de blocos /dev/sr0 é protegido contra gravação; montando somente para leitura
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
Em alguns casos informações úteis são encontradas no syslog - tente
"dmesg | tail" ou algo do tipo
