[0]Hi,
[0]
[0]I have just succeeded in getting the matcd driver from current to work 
[0]with my (still
[0]somewhat 2.0 ALPHA) system, but now I was trying to play an audio cd.
[0]
[0]>From what I understand it should be possible, but I can get neither
[0]xcd nor xcdplayer to work.

The problem is that all the audio-related ioctls aren't written yet.
I wrote the driver and the FreeBSD powers really wanted it in 2.1
(which was planned for March) so I focused on getting the non-audio stuff
done first.   The remaining ioctls and the man page are on the way.

By the way, you can play audio all day long using the program "cdplayer".

I had four or five CD-players all playing audio at the same time during
tests.  It sounded like a scene from Star Trek TNG where Data is listening
to several compositions all at once.  I can now recommend some of the 
stranger combinations of music to play together.  

FYI, The driver will support 16 drives.

Note that cdplayer (what I used and got off the net) isn't an X program but
I don't think that has anything to do with it.  Apparently the two programs
you mentioned are using some of the ioctls that aren't done yet, such as
the one to play discs in mono or determine if a track is in XA format.
Cdplayer is pretty stupid and doesn't get upset if an ioctl isn't
available.  It just goes on to the next.

I am adding these ioctls daily and hope to be done shortly.

But, I have been trying to get some information on exactly what some of the
missing ioctls are supposed to do as there is no documentation and there
are mistakes in the existing cdio.h include file.  I have several
feelers out for assistance on this, so hopefully someone will reply.

Please write to me direct regarding the symptoms you are encountering
in xcd / xcdplayer and perhaps this will help me out. 

Oh yes, use   uhclem%nemesis@fw.ast.com   or your mail will take weeks to
get here  (stupid domain mail server!).  This address takes maybe an hour.
