Okay, I'm replying to this e-mail in the chain, just because I think
everything is getting a little muddy further on.

The GNOME-CD player will not pull the data off of the drive and put it
into the sound card. Yes, this is annoying. Many computers do not
connect the sound from a CD-ROM to the sound card - for various
reasons. I don't know that they are good ones, but they do this none
the less. I'm quite sure that both Mac OS and Windows deal with this
gracefully.

Why isn't this done properly in GNOME-media? Well, mostly because of
lack of time. There is a Solaris patch to fix this in bugzilla, but
I've denied it because it works around where GNOME-media should be going
- to be all Gstreamer based. So what really needs to happen is there
needs to be a Gstreamer input plug-in written that pulls data off of the
drive - then it can go through the rest of the pipeline. I believe
there is one started, I'm not sure it's complete.

I'm not sure about other Linux CD players - I imagine that there is one
out there that can pull the data off of the drive and play it. Perhaps
the KDE cd-player will. I can only confirm that today, the GNOME one
will not.
