Try this:
1. Create a new Project with 24-bits.
2. Record some audio into it. Ideally, use AES and import a digital 24-bit file from some digital 24-bit source. If not, record analog (I believe it will record 24-bit in this project).
3. Edit as needed and do File menu
Save As SF. Make sure you select SF, NOT Save As Wav as it saves 16-bits only.
4. Take whatever CDROM writing software you have and copy this SF file to a CDROM disc.
5. Delete the saved 24-bit SF file.
6. Create a new 24-bit project.
7. Click the Segment menu, Create Segment command.
8. Select the CDROM drive for your drive, and locate your 24-bit SF file.
9. Create a segment from it.
10. Play the project.
I think it will work.
