Has the OP tried playing using cdda2wav an example
$ cdda2wav -eN dev=/dev/sr0 -t1
plays track 1 from cdrom0,
It can play from command line and get information from
cd,
[olivares at localhost ~]$ cdda2wav -eN dev=/dev/sr1 -t1

a seperate file.
-paranoia use the lib paranoia
for reading.
-paraopts=opts set options for lib
paranoia (see -paraopts=help).
-cddbp-server=servername set the cddbp server
to use for title lookups.
-cddbp-port=portnumber set the cddbp port to
use for title lookups.
-version print version
information.
Please note: some short options will be phased out
soon (disappear)!
parameters: (optional) one or more file names or - for
standard output.
Version 1.1.6
defaults stereo, 16 bit, 44100.00 Hz, track 1,
no offset, one track,
type wav 'audio', don't wait for signal, not
quiet,
use generic_scsi, device /dev/cdrom, aux
/dev/cdrom
[olivares at localhost ~]$
If this does not work, please let me know. It has
worked for me in the past. It lets you also rip the
cd to wav files which can later be burned to make a
non protected cd for your personal use.
