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: drive name: hdb hda drive speed: 48 48 drive # of slots: 1 1 Can close tray: 1 1 Can open tray: 1 1 Can lock tray: 1 1 Can change speed: 1 1 Can select disk: 0 0 Can read multisession: 1 1 Can read MCN: 1 1 Reports media changed: 1 1 Can play audio: 0 1 Can write CD-R: 1 1 Can write CD-RW: 1 1 Can read DVD: 1 1 Can write DVD-R: 1 1 Can write DVD-RAM: 1 1 Can read MRW: 1 1 Can write MRW: 1 1 Can write RAM: 1 1 log/messages: Oct 4 09:27:01 sauron kernel: hda: UDMA/66 mode selected Oct 4 09:27:01 sauron kernel: hdb: UDMA/66 mode selected Oct 4 09:27:01 sauron kernel: hda: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache Oct 4 09:27:01 sauron kernel: Uniform CD-ROM driver Revision: 3.20 Oct 4 09:27:01 sauron kernel: hdb: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache /log/syslog Oct 4 09:27:01 sauron kernel: hda: TSSTcorp CDDVDW SH-S202J, ATAPI CD/DVD-ROM drive Oct 4 09:27:01 sauron kernel: hdb: Optiarc DVD RW AD-7200A, ATAPI CD/DVD-ROM drive 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: http://ubuntuforums.org/showthread.php?t=675812 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.
