Can't play any CD+G?

[sigma]

I have writen ASPI drivers.
That drive supports CD+G, I'm quite sure.
I have made it work with My own stuff for testing purposes.
I bought this software for usability reasons.
My ASPI work is quite old and I want to stop using My old
computers.

Okay, I could understand the CDR being a problem if I was
writing the disc.
I can't play the tracks even when I don't write the disc.
Since I can't play the tracks at all, even with NO drive selected
I fail to see how the CDR relates to this problem.
It is almost like the play commands to DirectX and DirectSound
are corrupt, I can't play any CD+G from the HDD or the CD at
all.
I have DirectX9 installed.
I have sound and video acceration off on 3 entirely different
computers.

Am I missing something? Shouldn't I be able to play a CD+G
from the HDD with this software even if there are NO CDROMs
or CDRs?

Thanx
