Oh, ok. I was under the impression that the digital connector was pretty standard these days. I have a miscellaneous TEAC CD-ROM drive and I'm using the digital connector with my SBLive and it works fine. IIRC, it worked with just the analogue connector too. > This may mean you have to set something in the mixer. What Linux calls > it for your SB-Live I don't know.

I'm using ALSA, and with aumix and the OSS emulation it's just the 'CD' (and the main master volume, of course) channel that has to be turned up. alsamixer also lists a CD channel, so crank that up see if it helps. > So if you're really unlucky you may have to hack the kernel modules.

For a while there, Creative was on the right track with their emu10k1 drivers. They hired a guy to do it, and GPL'd the code, but kept the actual documentation under an NDA but actually let people sign up for it. It seemed like they were actually going to Free the specs, but then opensource.creative.com shut down, the dude was fired and development moved to sourceforge. So, yeah, not all that Free Software friendly, but they are (or were, at least) trying harder than NVidia, f'r instance. > If you don't mind the load you might try playing CDs "through the > computer" with something like what I use (not very often, cos I > usually play them through the hi-fi): > > cdda2wav -q -e -D/dev/cdrom -N -B 2>/dev/null & > > (that's for CD-ROM on ide-cd; if yours is ide-scsi use cdrecord > -scanbus to get the n,n,n parameters for -D ) Good idea, but I really think that you can get CDDA working. -rob
