Possible, but the CD-sound card cable is a basic analog cable, so it's really hard to connect it wrong. Often you have to enable the CD input in your sound card mixer so the sound card actually listens to what the CD says. Have you checked this? A good thought. CD was set to low volume but not zero. I set it high and still got no output. -- ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

My latest thought, however: Does FreeDOS and/or a certain CD player support sending the sound digitally to the sound card over the ribbon cable and the PC bus, the way modern Windows does it? In this case I can dispense with the cable. As I wrote earlier already, MPXPLAY does exactly that (but it comes with a higher CPU usage, than using hardware capabilities of your CD player of course).

Re: [Freedos-user] Avoid the analog audio CD cable?
I've been following this thread for some reason, and I finally figured out why. I think I had a similar multimedia PC my parents bought for me about 20 years ago (486SX 33MHz, 4MB RAM, 200MB HD, 2X CD-ROM and Sound Card when these were still considered optional, DOS 6.22/Windows 3.11). And I remember getting Front Page Sports Football Pro 95, Wolfenstein, and Doom working on this. Anyways, someone on VOGONS did a ton of research [0] on similar sound cards. I suggest reading it.

Re: [Freedos-user] Avoid the analog audio CD cable?
I plowed all the way through the (interesting) article but didn't read anything that seemed to help me. Most of it is about the Pro Audio Spectrum (PAS) lineup. In the meantime I installed a Win 98 hard drive on this machine and got the sound card working in Windows. But I found out that digital audio extraction does not work -- it required the analog audio CD cable. Digital audio extraction must have debuted in Win Me or XP. On the bright side, I got the analog audio CD cable working in Windows. So now I know that I have a good hardware hookup. But when I returned to FreeDOS with this now-known-good cable connection, my two CD players still failed just as before.
