Playing audio CD on ULTRA 5/10

[Gabor Zoltan Csejtey <Gabor.Csejtey@idi.ntnu.no>]

I have an IDE cdrom (from dmesg):

CRD-8240B, ATAPI CDROM drive
ATAPI 24X CD-ROM drive, 128kB Cache
Uniform CD-ROM driver Revision: 3.11

I can mount ISO9660 filesytems on it and play audio CD-s using the
headphone plug. But I cannot access the CD from any CDplayers which I
tried:

e.g. xmcd, gcd, cccd, gtcd etc.

I configured xmcd with xmcdconfig and I have found the 
Sun ATAPI/IDE Goldstar CRD-8240 drive there but it doesn't work.

gcd gives the following message:
Error: Failed to read disc contents

I can use the eject button nothing else with these CDplayers

PS.

I made a symlink /dev/cdrom -> /dev/hdc
which works fine with mount.
