Virtual drive and audio cd's

Why are my audio CD images (clonecd) not working in the virtual drive of cloneCD after mounting the image to the virtual drive ?
Other images are working correct.
Using latest version of CloneCD.

do they work in Daemon Tools?
Do they burn OK?

Thanks for response !

I haven’t test it in deamon tools. I will try.
The images burn OK with cloneCD.

Yes, the audio images works with deamon tools.

Wonder why not with virtual drive of CloneCD ?

At the moment there appear to be better VDs around.
