I got a CT4780 Sblive card. It works with both sound and midi in dos 6.22 and 7. There is a test in the Descent 2 sound setup with a test for redbook audio. I was always curious what the cable was for from the cdrom to the card. I have both the analog 4 pin and the digital 2 pin hooked up. I get zilch from the test, it actually dosen't look like the cd is even being accessed. But if I run the game it uses it. I have no way of knowing if its a faulty cd, or a driver issue. Is there any other way to test that the cable and cd and drivers are setup to play this cd-audio track format and that its working right ? Is there any other test utility specificly for this ?

To test the setup you can use any audio player software that supports playing CDs. Usually CDs that combine data+redbook put the music on track 2 and later.
Try a standard music CD, those should work too.
I've never programmed CD stuff but I doubt any driver is even needed for this.
The music tracks on the disc can be tested in any CD player. Redbook is just a standard audio track that all CD players can play.

Some drives have a play button on the front, if you push that button then the analog audio cable is the only way you'll hear it. If you play through software in Windows, then sometimes Windows might be set up to send the data digitally over the data cable instead of using the analog audio cable.

Ok, yes, confirmed the images and tracks are good, decent 2 and carmageddon play in xp media player under cd. Ran the descent 2 game and the option menu showed midi or cd audio not set by default,
So midi and cd-audio can't coexist at the same time ?, Dos can handle only one digital format at a time ? Does this mean the tester tool for descent 2 just dosen't work?
The best tester tool would be a vlc player or mplayer type program for dos that plays regular cd music, is there a media player program for Dos ?

They can but Descent 2 they're completely different soundtracks and there's no logical reason for playing both of them at once. It's not out of a technical limitation.

Sound Blaster card software often had a CD player in the SB16 era at least.

Ok, found it. there is a whole lot of media players, I was surprised. Now I can play all of my music without being afraid apple will delete my tunes, Apple can't touch my Dos drive.

I got to ask dxx rebirth if they can extract the red book audio and play that instead of the midi

Some of the redbook music in these games rock I agree, looks like I am going to start another OCD collection ... midi tunes and redbook
