Subject: New CD/DVD reports 'Can Play Audio    NO'


Hi all,

Very strange issue.  I recently bought a new machine that came with a
CD/DVD burner.  All functions normally, except I cannot play audio CD.

Information:

Slackware 12.1 running latest stable kernel 2.6.26.5

The drive is:

Vendor                      : Optiarc 
Model                       : DVD RW AD-7200A 
Revision                    : 1.06

Now, I have another drive (I purchased last year) that could play audio
CD, so I installed that as master, and put the new drive as slave
(old->hda new->hdb).  The old(er) drive can and does play audio OK.

I see this in /proc/sys/dev/cdrom/info:

I have investigated this, but can't find any information at all - there
are very few hits doing a search, but relevant pages I found are:

D. Bray filled a very verbose bug report of a similar issue:
http://lists.debian.org/debian-user/2008/09/msg01696.html

A Gentoo user with the same drive reports another issue, but his CDROM
info dump also reports this model cannot play audio CDs:
http://bugs.gentoo.org/show_bug.cgi?id=218413

A Ubuntu user with the same drive also rpeorts audio CDs cannot be
played:

Myself and D. Bray had a discussion on this, and we both feel this
could be a kernel issue.

I would be able to debug this issue if required.

Thanks,

Nick
