No worries, I appreciate you taking the time to reply.
But good news (for me at least), I managed to get CD audio playing using the CompactDisk library functions in WinUAE emulating the CD32, haven't tested on my hardware CD32 yet though. The functions need to be called in Amiga/QAmiga mode. Switching to Blitz mode instantly after starting playback caused the playback not to start, having a delay before switching back to Blitz mode seems to work. This still needs more testing but anyway here is the code for future references.
Code:
; CD32 CD Audio test
; CDStatus bit definitions
#CDSTSB_CLOSED = 0 ; Drive door is closed
#CDSTSB_DISK = 1 ; A disk has been detected
#CDSTSB_SPIN = 2 ; Disk is spinning (motor is on)
#CDSTSB_TOC = 3 ; Table of contents read. Disk is valid.
#CDSTSB_CDROM = 4 ; Track 1 contains CD-ROM data
#CDSTSB_PLAYING = 5 ; Audio is playing
#CDSTSB_PAUSED = 6 ; Pause mode (pauses on play command)
#CDSTSB_SEARCH = 7 ; Search mode (Fast Forward/Fast Reverse)
#CDSTSB_DIRECTION = 8 ; Search direction (0 = Forward, 1 = Reverse)
; Print at location with colour
Statement PrintAt{x.w, y.w, col.b, text$}
Locate x,y : Colour col : Print text$
End Statement
