there are 3 different ways of playing sound from a CD.

1) Using the analog audio cable from the CD drive to your pc's sound
card.

2) Some CD drives have a digital sound output from the CD drive to the
sound card. Don't think this is used much....

3) Digital playback - using software, your program reads the data
directly from the CD, then plays it on the computer.


Traditionally, most linux programs used option 1 for playing audio CDs.
However, because lots of manufactures don't bother putting audio cables
in these days, the newer programs use software (cdparanoia, I think) to
read the data, then play it (option 3).

This also produces better quality sound - even on the crappiest of CD
drive, the sound is the best it can be, since the CD drive sound output
is not bing used. The data is read directly, then played. The quality is
limited by your soundcard, rather than some piece-of-sh**t drive.

However, older versions of CD playing software often don't support this
feature... In the case of GNOME, I think it was added in 2.4. In terms
of KDE, I'm not sure.

In the case of your program not supporting option 3, the fix can be
tricky, since you really need to upgrade. If you know a bit of C, you
could try back porting the feature... if you search the web, you might
find community packages that add this feature.
