I have now, thanks, he says with a red face. As I mentioned in earlier
replies, though the Gnome CD player, gtcd, now works OK, XMMS still does
not see the audio CD. Since XMMS played audio CD's just fine using the
ATAPI CD-R (which still shows up in dmesg, though the laser died), I
have obviously gotten something simple screwed up. I'll keep trying.

I haven't tried either of the above suggestions yet, but I did try to
burn a CD from the command line, unsuccessfully. Not only was it an
unsuccessful attempt, but I locked up my machine hard. First time I have
done that in a long time. "cdrecord" started out OK, and reported all
the correct data re the drive, media and iso file, but just after the
warning that the burn would start, and it reported the buffer was ready,
there was a message re "OPC" and then the machine locked up, with the
hard drive light on, and of course, nothing burned. Scanbus reports the
hard drives and the burner correctly. When I check dmesg, the burner is
reported as "sr0", and identified correctly.

When I look in /proc/devices both "sr" and "sg" are shown as block
devices. If I do a "ls -l" for the devices, I get the following:
lrwxrwxrwx 1 root cdrom 4 Mar 8 14:21 /dev/cdrom ->
scd0
brw-rw---- 1 root cdrom 11, 0 Jun 13 2001 /dev/scd0
crw------- 1 root root 21, 0 Jun 13 2001 /dev/sg0
brw-rw-rw- 1 root cdrom 11, 0 Mar 5 19:57 /dev/sr0
Do I need to have two devices at work here, i.e., scd0 for the reader
and scd1 for the burner?

I tried both of these commands as root after getting the same error
message with RealPlayer, and neither returned anything. Since RealPlayer
worked the other day, not sure what has gotten munged up.

Thanks again for all of the help and suggestions.
> /me gets an idea for the weekend
Hope your weekend has been a great one and your idea worked out as you
planned. It has been a very cold, damp day here, so not a bad day to be
messing about with computers and troubleshooting, even if all not
solved. At least I have one more day of the weekend to go, and to work
around with this problem. Not sure what I will try next, but I will do a
little more reading and see what I can work out.
