[gentoo-user] Can't play audio cds!

[Michael Sullivan]

I can't play audio cds.  I used to use gnome-cd, but that seems to be
gone now, and none of the other CD players will play sound.  KsCD will
even show the track titles on the CD, but it won't play sound.  I
checked the log file, but I couldn't find anything.  I couldn't mount my
CD (in the past this wasn't necessary for audio CDs, but I thought I'd
try it anyway), and then I got something in the log.  My /dev/cdrom is a
link to /dev/hda:

camille ~ # grep /dev/hda /var/log/messages
Oct  6 11:41:41 camille GFS2: Unrecognized block device or mount
point /dev/hda
Oct  6 11:42:13 camille GFS2: Unrecognized block device or mount
point /dev/hda
Oct  6 11:42:35 camille GFS2: Unrecognized block device or mount
point /dev/hda

camille ~ # ls -l /dev/hda
brw-rw---- 1 root cdrom 3, 0 Oct  6 07:06 /dev/hda

and I am in the cdrom group:

camille ~ # grep cdrom /etc/group
cdrom:x:19:michael,haldaemon

and the audio group:

camille ~ # grep audio /etc/group
audio:x:18:amy,michael,mythtv

I rebooted into Windows XP, where the same CD played just fine.  Can
anyone tell me what's going on with this?

As far as I know, the Linux kernel cannot mount Audio CDs. The one
programme that on my system works with Audio CDs is Gnome-mplayer. You
might also try VLC. Another option is to rip them with Grip.

I can play an audio CD (with Beethoven music) with mplayer cdda://.
Can you try a program that I or Liviu Andronic know? That way, we
would more likely understand the error messages, assuming it does not
work and gives error messages.
How about you try gnome-mplayer?

I wrote in about this problem awhile ago and never got an answer.  This
morning I was googling the problem and came across the thread I created
on an archive site and looked at it just to see if there was anything
I'd missed.  There was a reply to it that I hadn't seen before, so I
read it.  I don't know why I never received the reply, but it suggested
using 

mplayer cdda://

and posting the error messages.  I tried it and it works; it plays my
audio cd:

However, kscd does not.  The interface looks like it's playing, but
there's no audio output:

As far as I can tell, the logs have nothing to say about this problem.
Unless I'm looking in the wrong log.  I checked /var/log/messages and
there is no mention of kscd anywhere. dmesg has the same two lines
repeated over and over again:

i2c-adapter i2c-1: master_xfer[1] R, addr=0x40, len=3
i2c-adapter i2c-1: master_xfer[0] W, addr=0x40, len=2

with one variation at the very top:  adapter i2c-1: master_xfer[1] R,
addr=0x40, len=2

If I try to play my CD in VLC, I get this error:  

Your input can't be opened:

VLC is unable to open the MRL 'cdda:///dev/hda'. Check the log for
details.


but I can't find VLC's log file.  Can anyone clue me in to where it is?

I checked /dev/hda (which IS my cd-rom drive):

camille ~ # ls -l /dev/hda
brwxrwxrwx 1 root cdrom 3, 0 Dec 28 15:15 /dev/hda


and I AM in the cdrom group:

camille ~ # grep cdrom /etc/group
cdrom:x:19:michael,haldaemon




I'm using gnome:

camille log # emerge -pv gnome

These are the packages that would be merged, in order:

Can anyone help me fix this with this new information?
