DVD-A is quite new but I though DT 3.23 would support it

However it seems it does not :cry:
(Note: I cannot install DT 3.26 under Windows .NET Pre-RC2)

I made a ISO-file from a original "Creative DVD-Audio Sampler Disc" which you get with an Audigy2 soundcard.
The ISO is mounted in DT 3.23 and correctly discovered by the Creative Audio DVD-Player.

The problem is that no sound arrives out of the boxes.
Everything is cross-checked and for me it seems like DT 3.23 has no Digial-Audio output. The "Analog-Audio" function has no effect, if enabled or disabled.
